Crystal structure of alfalfa feruoyl coenzyme A 3-O-methyltransferase
|
Overview
Caffeoyl coenzyme A 3-O-methyltransferases (CCoAOMTs) are, S-adenosyl-l-methionine-dependent O-methyltransferases (OMTs) involved in, lignin biosynthesis. Plant CCoAOMTs belong to a distinct family of OMTs, more closely related to the mammalian catechol OMTs than to other plant, OMTs. The crystal structure of alfalfa (Medicago sativa) CCoAOMT in, complex with the reaction products S-adenosine-l-homocysteine and, feruloyl/sinapoyl CoAs presented here belong to a structurally and, mechanistically distinct family of plant small molecule OMTs. These, structures provide a new understanding of the substrate preferences and, the catalytic mechanism accompanying CCoAOMT-mediated O-methylation of, CoA-linked phenylpropanoid substrates.
