cDNA encoding C. elegans Delta6 desaturase has been cloned and sequenced, and the Delta6 desaturase amino acid sequence has been determined: The C. elegans Delta6 desaturase has a surprisingly low level of sequence identity with the known borage Delta6 desaturase. The C. elegans Delta6 desaturase has been expressed in yeast. It and other desaturases can be cloned in host organisms (e.g. plants) and can be used to provide useful metabolites
