Biotin and lysine
WebBPL transfers the biotin to a special lysine on biotin carboxyl carrier protein (BCCP), a subunit of AcCoA carboxylase (Scheme 21 ). 135 Biotinylation of BCCP is very important in fatty acid biosynthesis, starting the growth of the fatty acid with AcCoA carboxylase to generate malonyl-CoA. WebBiotin and many fluorescent compounds naturally contain or are easily synthesized with a carboxyl group, which can be easily derivatized using carbodiimide chemistry (usually …
