Rosmarinate synthase

Jump to: navigation, search

In enzymology, a rosmarinate synthase (EC 2.3.1.140) is an enzyme that catalyzes the chemical reaction

caffeoyl-CoA + 3-(3,4-dihydroxyphenyl)lactate CoA + rosmarinate

Thus, the two substrates of this enzyme are caffeoyl-CoA and 3-(3,4-dihydroxyphenyl)lactate, whereas its two products are CoA and rosmarinate.

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 caffeoyl-CoA:3-(3,4-dihydroxyphenyl)lactate 2'-O-caffeoyl-transferase. Other names in common use include rosmarinic acid synthase, caffeoyl-coenzyme A:3,4-dihydroxyphenyllactic acid, caffeoyltransferase, and 4-coumaroyl-CoA:4-hydroxyphenyllactic acid 4-coumaroyl transferase. This enzyme participates in tyrosine metabolism.
