CYANOBACTERIAL DELTA 6-DESATURASE, NUCLEIC ACID ENCODING THE SAME AND PROCESS FOR PRODUCING DELTA 6- DESATURASE INDUCING THE GAMA-LINOLENIC ACID PRODUCTION

摘要

Linoleic acid is converted into gamma -linolenic acid by the enzyme DELTA 6-desaturase. The present invention is directed to an isolated nucleic acid comprising the DELTA 6-desaturase gene. More particularly, the isolated nucleic acid comprises the promoter, coding region and termination regions of the DELTA 6-desaturase gene. The present invention provides recombinant constructions comprising the DELTA 6-desaturase coding region in functional combination with heterologous regulatory sequences. The nucleic acids and recombinant constructions of the instant invention are useful in the production of GLA in transgenic organisms.
