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 acyltransferases 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.
