LITERATURE
evolution
sinapine esterase is classifed as a member of the SGNH hydrolase subfamily of GDSL-lipases which cleave ester bonds in a wide array of lipids
metabolism
1-O-sinapoylglucose, produced by UDP-glucose:sinapate glucosyltransferase during seed development, is converted to sinapine by sinapoylglucose:choline sinapoyltransferase and hydrolyzed by sinapoylcholine (sinapine) esterase in germinating seeds. The released sinapate feeds via sinapoylglucose into the biosynthesis of sinapoylmalate in the seedlings catalyzed by sinapoylglucose:L-malate sinapoyltransferase. Pathway of sinapate ester biosynthesis, overview
physiological function
sinapoylmalate is involved in protecting the leaves against the deleterious effects of UV-B radiation. Sinapine might function as storage vehicle for ready supply of choline for phosphatidylcholine biosynthesis in young seedlings
