all members of the CSFAD2 and CSD6 subclasses of microsomal desaturases consist of a single exon. Evolutionary relationship of Cannabis sativa putative desaturases, overview
evolution
in plants, membrane-bound fatty acid desaturases are present in the plastid and the endoplasmic reticulum. The electron donors for plastid desaturases are typically ferredoxins, while endoplasmic reticulum enzymes use cytochrome b5 (Cytb5)

physiological function
fatty acid desaturases, FADs, play an essential role in fatty acid metabolism and the maintenance of biological membranes
physiological function
the DELTA12-fatty acid desaturase gene is absolutely essential for the biosynthesis of linoleic acid as the main substrate for lipid peroxidation
physiological function
-
inserted heterologous desA gene for DELTA12 acyl-lipid desaturase in potato plants results in improved tolerance of transformants to oxidative stress due to the more efficient maintenance of stable cell membrane structure functioning, and this permits prevention of electron jump to oxygen and, as a result, of accelerated reactive oxygen species generation
physiological function
overexpression of the acyl-lipid DELTA12-desaturase in transformed potato plants promotes fatty acid polyunsaturation and presumably averts the accelerated generation of the superoxide anion, thus suppressing lipid peroxidation under low-temperature stress
physiological function
recombinant enzyme expression improves potato plant resistance to Phytophthora infestans infection
physiological function
Solanum tuberosum plants expressing Synechocystis DELTA12-acyl-lipid desaturase experience less severe thermal and oxidative stress upon cooling and can cope with the cold without considerable increase in the enzyme activity
physiological function
the enzyme increases the tolerance to low temperature
physiological function
the expression of DELTA12 acyl-lipid desaturase positively influences stabilization of not only structure but also functioning of chloroplast membranes in Solanum tuberosum, thus preventing a transfer of electrons from the electron transport chain to oxygen and subsequent reactive oxygen species generation at hypothermia
physiological function

physiological function
in plants, seed-specific delta-12 fatty acid desaturase 2 (FAD2) is responsible for the high content of linoleic acid by inserting a double bond at the delta-12 (omega-6) position of oleic acid.
