Lydicamycin is an antibiotic first isolated from Streptomyces. It is particularly cytotoxic against S. aureus, including the methicillin resistant 535 strain (MICs = 3.1-6.2 µg/ml). Lydicamycin also inhibits the growth of C. neoformans (MIC = 25 µg/ml) but is ineffective against Gram-negative bacteria.

Lydicamycin, a new antibiotic of a novel skeletal type. II. Physico-chemical properties and structure elucidation
J Antibiot (Tokyo) 1991 Mar;44(3):288-92.PMID:2026554DOI:10.7164/antibiotics.44.288.
The structure of a new antibiotic designated Lydicamycin was elucidated as shown in Fig. 1 by NMR spectral analysis including a variety of 2D techniques. Lydicamycin possesses a novel skeleton containing tetramic acid and amidinopyrrolidine moieties.
Lydicamycin, a new antibiotic of a novel skeletal type. I. Taxonomy, fermentation, isolation and biological activity
J Antibiot (Tokyo) 1991 Mar;44(3):282-7.PMID:2026553DOI:10.7164/antibiotics.44.282.
A novel antibiotic, designated Lydicamycin, was isolated from the fermentation broth of an actinomycete strain identified as Streptomyces lydicus. Lydicamycin was active against Gram-positive bacteria and a certain yeast, but inactive against Gram-negative bacteria.
TPU-0037-A, B, C and D, novel Lydicamycin congeners with anti-MRSA activity from Streptomyces platensis TP-A0598
J Antibiot (Tokyo) 2002 Oct;55(10):873-80.PMID:12523820DOI:10.7164/antibiotics.55.873.
In screening for anti-MRSA antibiotics, novel Lydicamycin congeners, TPU-0037-A, B, C and D, were isolated from a culture broth of an actinomycete strain. The producing strain, TP-A0598, was isolated from a seawater sample collected in Toyama Bay, Japan, and identified as Streptomyces platensis based on taxonomic characteristics. TPU-0037-A, B, C and D were purified by HP-20 resin, ODS column chromatographies and preparative HPLC, consecutively, and their structures were determined to be 30-demethyllydicamycin, 14,15-dehydro-8-deoxylydicamycin, 30-demethyl-8-deoxylydicamycin and 8-deoxylydicamycin, respectively, by NMR and MS analyses. The new congeners showed antibiotic activity against gram-positive bacteria including MRSA with the MIC of 1.56 to approximately 12.5 microg/ml.
Draft genome sequence of marine-derived Streptomyces sp. TP-A0598, a producer of anti-MRSA antibiotic lydicamycins
Stand Genomic Sci 2015 Aug 26;10:58.PMID:26380643DOI:10.1186/s40793-015-0046-5.
Streptomyces sp. TP-A0598, isolated from seawater, produces Lydicamycin, structurally unique type I polyketide bearing two nitrogen-containing five-membered rings, and four congeners TPU-0037-A, -B, -C, and -D. We herein report the 8 Mb draft genome sequence of this strain, together with classification and features of the organism and generation, annotation and analysis of the genome sequence. The genome encodes 7,240 putative ORFs, of which 4,450 ORFs were assigned with COG categories. Also, 66 tRNA genes and one rRNA operon were identified. The genome contains eight gene clusters involved in the production of polyketides and nonribosomal peptides. Among them, a PKS/NRPS gene cluster was assigned to be responsible for Lydicamycin biosynthesis and a plausible biosynthetic pathway was proposed on the basis of gene function prediction. This genome sequence data will facilitate to probe the potential of secondary metabolism in marine-derived Streptomyces.
Streptomyces lydicamycinicus sp. nov. and Its Secondary Metabolite Biosynthetic Gene Clusters for Polyketide and Nonribosomal Peptide Compounds
Microorganisms 2020 Mar 6;8(3):370.PMID:32155704DOI:10.3390/microorganisms8030370.
(1) Background: Streptomyces sp. TP-A0598 derived from seawater produces Lydicamycin and its congeners. We aimed to investigate its taxonomic status; (2) Methods: A polyphasic approach and whole genome analysis are employed; (3) Results: Strain TP-A0598 contained ll-diaminopimelic acid, glutamic acid, glycine, and alanine in its peptidoglycan. The predominant menaquinones were MK-9(H6) and MK-9(H8), and the major fatty acids were C16:0, iso-C15:0, iso-C16:0, and anteiso-C15:0. Streptomyces sp. TP-A0598 showed a 16S rDNA sequence similarity value of 99.93% (1 nucleottide difference) to Streptomyces angustmyceticus NRRL B-2347T. The digital DNA-DNA hybridisation value between Streptomyces sp. TP-A0598 and its closely related type strains was 25%-46%. Differences in phenotypic characteristics between Streptomyces sp. TP-A0598 and its phylogenetically closest relative, S. angustmyceticus NBRC 3934T, suggested strain TP-A0598 to be a novel species. Streptomyces sp. TP-A0598 and S. angustmyceticus NBRC 3934T harboured nine and 13 biosynthetic gene clusters for polyketides and nonribosomal peptides, respectively, among which only five clusters were shared between them, whereas the others are specific for each strain; and (4) Conclusions: For strain TP-A0598, the name Streptomyces lydicamycinicus sp. nov. is proposed; the type strain is TP-A0598T (=NBRC 110027T).
