Accepted name: tartronate O-hydroxycinnamoyltransferase

Reaction: sinapoyl-CoA + 2-hydroxymalonate = CoA + sinapoyltartronate

sinapic acid = 4-hydroxy-3,5-dimethoxycinnamic acid
tartonic acid = 2-hydroxymalonic acid

Other name(s): tartronate sinapoyltransferase; hydroxycinnamoyl-coenzyme-A:tartronate hydroxycinnamoyltransferase

Systematic name: sinapoyl-CoA:2-hydroxymalonate O-(hydroxycinnamoyl)transferase

Comments: 4-Coumaroyl-CoA (4-hydroxycinnamoyl-CoA), caffeoyl-CoA (3,4-dihydroxycinnamoyl-CoA) and feruloyl-CoA (4-hydroxy-3-methoxycinnamoyl-CoA) can also act as donors for the enzyme from the mung bean (Vigna radiata).
