Cloning and characterization of a cDNA encoding diacylglycerol acyltransferase from castor bean
Lipids 2004 Apr;39(4):311-8.PMID:15357018DOI:10.1007/s11745-004-1234-2.
The oil from castor seed (Ricinus communis) contains 90% ricinoleate, a hydroxy FA that is used in producing numerous industrial products. Castor diacylglycerol acyltransferase (RcDGAT) is a critical enzyme, as it catalyzes the terminal step in castor oil biosynthesis in which the products contain two or three ricinoleoyl moieties. We have isolated a cDNA encoding RcDGAT from developing castor seeds. Analysis of the sequence reveals that this cDNA encodes a protein of 521 amino acids with a molecular mass of 59.9 kDa. Although there are regions of high similarity to other plant DGAT coding sequences, there are sequences that distinguish it as well. Southern blot analysis suggests that the castor genome contains a single copy of RcDGAT. Analysis by reverse transcription-PCR reveals that the accumulation of the mRNA reaches its highest level at 19 d after pollination and declines thereafter. Expression of the full-length cDNA for RcDGAT in the yeast Saccharomyces cerevisiae, strain INVSc1 results in sevenfold higher DGAT activity compared with controls. When different molecular species of DAG were provided as substrates to the microsomal mixture, the RcDGAT showed a greater preference to catalyze the transfer of oleate from [14C]oleoyl-CoA to diricinolein than to diolein and Dipalmitolein. With the addition of 0.25 mM substrates, diricinolein gave 318 pmol/mg/min diricinoleoyloleoylglycerol (RRO), while diolein and Dipalmitolein gave only about 195 pmol/mg/min of triolein (OOO) and 120 pmol/mg/min dipalmitoyleoylglycerol (PoPoO), respectively. This work will facilitate investigation of the role of RcDGAT in castor oil biosynthesis.
