catalyzes Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recyc ...

the chemical reaction :1-O-sinapoyl-beta-D-glucose + (S)-malate

\rightleftharpoons

D-glucose + sinapoyl-(S)-malate Thus, the two substrates of this enzyme are 1-O-sinapoyl-beta-D-glucose and (S)-malate, whereas its two products are D-glucose and sinapoyl-(S)-malate. This enzyme belongs to the family of transferases, specifically those

acyltransferase Acyltransferase is a type of transferase enzyme that acts upon acyl groups. Examples include: * Glyceronephosphate O-acyltransferase * Lecithin-cholesterol acyltransferase *Long-chain-alcohol O-fatty-acyltransferase In enzymology, a long-chain- ...

s transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 1-O-sinapoyl-beta-D-glucose:(S)-malate O-sinapoyltransferase. Other names in common use include 1-sinapoylglucose-L-malate sinapoyltransferase, and sinapoylglucose:malate sinapoyltransferase. This enzyme participates in phenylpropanoid biosynthesis.
