Web23 sep. 2008 · The keto and enoyl reductases are encoded respectively by the YBR159w and TSC13/YDL015c genes; the condensing enzymes are coded by a small family of genes, ELO1, 2, and 3, of which ELO2/FEN1/YCR034w and ELO3/SUR4/YLR372w have been shown to be required for the synthesis of VLCFAs ( 5 ).
KSs exist as individual enzymes, as they do in type II fatty acid synthesis and type II polyketide synthesis, or as domains in large multidomain enzymes, such as type I fatty acid synthases (FASs) and polyketide synthases (PKSs). KSs are divided into five families: KS1, KS2, KS3, KS4, and KS5. Meer weergeven Ketoacyl synthases (KSs) catalyze the condensation reaction of acyl-CoA or acyl-acyl ACP with malonyl-CoA to form 3-ketoacyl-CoA or with malonyl-ACP to form 3-ketoacyl-ACP.
