Methyl anthranilate, a plant spice extract, is a quorum sensing inhibitor and anti-biofilm agent against Aeromonas sobria. Methyl anthranilate has been widely employed for the preparation of edible flavor and food additives in food processing industries[1].
0.5 μL/mL of Methyl anthranilate evidently reduces biofilm formation (51.44%), swinging motility (74.86%), swarming motility (71.63%), protease activity (43.08%), and acyl-homoserine lactone (AHL) production. Methyl anthranilate might inhibit quorum sensing (QS) system in A. sobria by interfering with the biosynthesis of AHL, as well as competitively binding with receptor protein[1].

Engineering of Saccharomyces cerevisiae for anthranilate and Methyl anthranilate production
Microb Cell Fact 2021 Feb 3;20(1):34.PMID:33536025DOI:10.1186/s12934-021-01532-3.
Background: Anthranilate is a platform chemical used by the industry in the synthesis of a broad range of high-value products, such as dyes, perfumes and pharmaceutical compounds. Currently anthranilate is produced via chemical synthesis from non-renewable resources. Biological synthesis would allow the use of renewable carbon sources and avoid accumulation of toxic by-products. Microorganisms produce anthranilate as an intermediate in the tryptophan biosynthetic pathway. Several prokaryotic microorganisms have been engineered to overproduce anthranilate but attempts to engineer eukaryotic microorganisms for anthranilate production are scarce. Results: We subjected Saccharomyces cerevisiae, a widely used eukaryotic production host organism, to metabolic engineering for anthranilate production. A single gene knockout was sufficient to trigger anthranilate accumulation both in minimal and SCD media and the titer could be further improved by subsequent genomic alterations. The effects of the modifications on anthranilate production depended heavily on the growth medium used. By growing an engineered strain in SCD medium an anthranilate titer of 567.9 mg l-1 was obtained, which is the highest reported with an eukaryotic microorganism. Furthermore, the anthranilate biosynthetic pathway was extended by expression of anthranilic acid methyltransferase 1 from Medicago truncatula. When cultivated in YPD medium, this pathway extension enabled production of the grape flavor compound Methyl anthranilate in S. cerevisiae at 414 mg l-1. Conclusions: In this study we have engineered metabolism of S. cerevisiae for improved anthranilate production. The resulting strains may serve as a basis for development of efficient production host organisms for anthranilate-derived compounds. In order to demonstrate suitability of the engineered S. cerevisiae strains for production of such compounds, we successfully extended the anthranilate biosynthesis pathway to synthesis of Methyl anthranilate.
Methyl anthranilate: A novel quorum sensing inhibitor and anti-biofilm agent against Aeromonas sobria
Food Microbiol 2020 Apr;86:103356.PMID:31703863DOI:10.1016/j.fm.2019.103356.
Quorum sensing (QS), bacterial cell-to-cell communication, is a gene regulatory mechanism that regulates virulence potential and biofilm formation in many pathogens. Aeromonas sobria, a common aquaculture pathogen, was isolated and identified by our laboratory from the deteriorated turbot, and its potential for virulence factors and biofilm production was regulated by QS system. In view of the interference with QS system, this study was aimed to investigate the effect of Methyl anthranilate at sub-Minimum Inhibitory Concentrations (sub-MICs) on QS-regulated phenotypes in A. sobria. The results suggested that 0.5 μL/mL of Methyl anthranilate evidently reduced biofilm formation (51.44%), swinging motility (74.86%), swarming motility (71.63%), protease activity (43.08%), and acyl-homoserine lactone (AHL) production. Furthermore, the real-time quantitative PCR (RT-qPCR) and in silico analysis showed that Methyl anthranilate might inhibit QS system in A. sobria by interfering with the biosynthesis of AHL, as well as competitively binding with receptor protein. Therefore, our data indicated the feasibility of Methyl anthranilate as a promising QS inhibitor and anti-biofilm agent for improving food safety.
Methyl anthranilate as a Repellent for Western Corn Rootworm Larvae (Coleoptera: Chrysomelidae)
J Econ Entomol 2016 Aug;109(4):1683-90.PMID:27122493DOI:10.1093/jee/tow090.
Methyl anthranilate was identified as the active compound in extracts of maize (Zea mays L.) roots that were shown to be repellent to neonate western corn rootworm (Diabrotica virgifera virgifera LeConte) larvae. A bioassay-driven approach was used to isolate the active material from diethyl ether extracts of roots from germinating maize seeds. Separation of the extract on a Florisil column yielded an active fraction of 90:10 hexane:diethyl ether. Analysis with gas chromatography-mass spectrometry identified two compounds in the active fraction: indole (2,3-benzopyrrole) and Methyl anthranilate (methyl 2-aminobenzoate). When tested in behavioral bioassays, Methyl anthranilate elicited a significant (P < 0.05) repellent response at doses of 1, 10, and 100 µg. In subsequent single-choice bioassays, 1, 10, and 100 µg of Methyl anthranilate prevented larvae from approaching 10 mmol/mol concentrations of carbon dioxide, which is normally highly attractive to the larvae. Indole, the other compound identified from the active fraction, did not elicit a behavioral response by the larvae. Methyl anthranilate has potential for development as a management tool for western corn rootworm larvae and may be best suited for use in a push-pull control strategy.
Genetic Analysis of Methyl anthranilate, Mesifurane, Linalool, and Other Flavor Compounds in Cultivated Strawberry ( Fragaria × ananassa)
Front Plant Sci 2021 May 19;12:615749.PMID:34093602DOI:10.3389/fpls.2021.615749.
The cultivated strawberry (Fragaria × ananassa) is an economically important fruit crop that is intensively bred for improved sensory qualities. The diversity of fruit flavors and aromas in strawberry results mainly from the interactions of sugars, acids, and volatile organic compounds (VOCs) that are derived from diverse biochemical pathways influenced by the expression of many genes. This study integrates multiomic analyses to identify QTL and candidate genes for multiple aroma compounds in a complex strawberry breeding population. Novel fruit volatile QTL was discovered for Methyl anthranilate, methyl 2-hexenoate, methyl 2-methylbutyrate, mesifurane, and a shared QTL on Chr 3 was found for nine monoterpene and sesquiterpene compounds, including linalool, 3-carene, β-phellandrene, α-limonene, linalool oxide, nerolidol, α-caryophellene, α-farnesene, and β-farnesene. Fruit transcriptomes from a subset of 64 individuals were used to support candidate gene identification. For methyl esters including the grape-like Methyl anthranilate, a novel ANTHANILIC ACID METHYL TRANSFERASE-like gene was identified. Two mesifurane QTL correspond with the known biosynthesis gene O-METHYL TRANSFERASE 1 and a novel FURANEOL GLUCOSYLTRANSFERASE. The shared terpene QTL contains multiple fruit-expressed terpenoid pathway-related genes including NEROLIDOL SYNTHASE 1 (FanNES1). The abundance of linalool and other monoterpenes is partially governed by a co-segregating expression-QTL (eQTL) for FanNES1 transcript variation, and there is additional evidence for quantitative effects from other terpenoid-pathway genes in this narrow genomic region. These QTLs present new opportunities in breeding for improved flavor in commercial strawberry.
Microbial production of Methyl anthranilate, a grape flavor compound
Proc Natl Acad Sci U S A 2019 May 28;116(22):10749-10756.PMID:31085637DOI:10.1073/pnas.1903875116.
Methyl anthranilate (MANT) is a widely used compound to give grape scent and flavor, but is currently produced by petroleum-based processes. Here, we report the direct fermentative production of MANT from glucose by metabolically engineered Escherichia coli and Corynebacterium glutamicum strains harboring a synthetic plant-derived metabolic pathway. Optimizing the key enzyme anthranilic acid (ANT) methyltransferase1 (AAMT1) expression, increasing the direct precursor ANT supply, and enhancing the intracellular availability and salvage of the cofactor S-adenosyl-l-methionine required by AAMT1, results in improved MANT production in both engineered microorganisms. Furthermore, in situ two-phase extractive fermentation using tributyrin as an extractant is developed to overcome MANT toxicity. Fed-batch cultures of the final engineered E. coli and C. glutamicum strains in two-phase cultivation mode led to the production of 4.47 and 5.74 g/L MANT, respectively, in minimal media containing glucose. The metabolic engineering strategies developed here will be useful for the production of volatile aromatic esters including MANT.
