Novel genes involved in petroselinic acid biosynthesis and method for producing petroselinic acid

摘要

Disclosed are a novel gene capable of promoting the accumulation of petroselinic acid and a process for producing petroselinic acid using the gene. A gene encoding any one of the following proteins (a), (b) and (c): (a) a protein comprising the amino acid sequence depicted in SEQ ID NO:4 or 6; (b) a protein which comprises an amino acid sequence having the deletion, substitution or addition of one or more amino acid residues in the amino acid sequence depicted in SEQ ID NO:4 or 6 and which has a petroselinoyl-ACP thioesterase activity; and (c) a protein which is encoded by DNA capable of hybridizing with DNA comprising a nucleotide sequence complementary to the nucleotide sequence depicted in SEQ ID NO:3 or 5 under stringent conditions and which has a petroselinoyl-ACP thioesterase activity.
