Fatty Acid Desaturases, Polyunsaturated Fatty Acid Regulation, and Biotechnological Advances
Polyunsaturated fatty acids (PUFAs) are considered to be critical nutrients to regulate human health and development, and numerous fatty acid desaturases play key roles in synthesizing PUFAs. Given the lack of delta-12 and -15 desaturases and the low levels of conversion to PUFAs, humans must consume some omega-3 and omega-6 fatty acids in their diet. Many studies on fatty acid desaturases as w...
متن کاملFATTY ACID DESATURASE4 of Arabidopsis encodes a protein distinct from characterized fatty acid desaturases.
Polar membrane glycerolipids occur in a mixture of molecular species defined by a polar head group and characteristic acyl groups esterified to a glycerol backbone. A molecular species of phosphatidylglycerol specific to chloroplasts of plants carries a Delta(3-trans) hexadecenoic acid in the sn-2 position of its core glyceryl moiety. The fad4-1 mutant of Arabidopsis thaliana missing this parti...
متن کاملExpression and Purification of Integral Membrane Fatty Acid Desaturases
Fatty acid desaturase enzymes perform dehydrogenation reactions leading to the insertion of double bonds in fatty acids, and are divided into soluble and integral membrane classes. Crystal structures of soluble desaturases are available; however, membrane desaturases have defied decades of efforts due largely to the difficulty of generating recombinant desaturase proteins for crystallographic a...
متن کاملSuppression of fatty acid synthase promoter by polyunsaturated fatty acids.
Dietary polyunsaturated fat is known to suppress expression of fatty acid synthase (FAS), a central enzyme in de novo lipogenesis. The sterol regulatory element-binding protein (SREBP) has recently been shown to be involved in this suppression. We previously reported that the first 2.1 kb of the FAS promoter are sufficient for transcriptional induction by a high carbohydrate diet as well as sup...
متن کاملPolyunsaturated fatty acid-specific elongation enzymes.
We have isolated a novel gene (GLELO) from Mortierella alpina and its homologue (CEELO1) from Caenorhabditis elegans and demonstrate the involvement of their encoded proteins in the elongation of C(18) polyunsaturated fatty acids.
