2.8.3.23

Accepted name:

caffeate CoA-transferase

Reaction:

3-(3,4-dihydroxyphenyl)propanoyl-CoA + (2E)-3-(3,4-dihydroxyphenyl)prop-2-enoate = 3-(3,4-dihydroxyphenyl)propanoate + (2E)-3-(3,4-dihydroxyphenyl)prop-2-enoyl-CoA

Glossary:

3-(3,4-dihydroxyphenyl)propanoate = hydrocaffeate
(2E)-3-(3,4-dihydroxyphenyl)prop-2-enoate = (2E)-3-(3,4-dihydroxyphenyl)acrylate = trans-caffeate

Other name(s):

CarA

Systematic name:

3-(3,4-dihydroxyphenyl)propanoyl-CoA:(2E)-3-(3,4-dihydroxyphenyl)prop-2-enoate CoA-transferase

Comments:

The enzyme, isolated from the bacterium Acetobacterium woodii, catalyses an energy-saving CoA loop for caffeate activation. In addition to caffeate, the enzyme can utilize 4-coumarate or ferulate as CoA acceptor.
