Reaction: (1) (E)-cinnamoyl-CoA + (R)-(phenyl)lactate = (E)-cinnamate + (R)-(phenyl)lactoyl-CoA
(2) (E)-4-coumaroyl-CoA + (R)-3-(4-hydroxyphenyl)lactate = 4-coumarate + (R)-3-(4-hydroxyphenyl)lactoyl-CoA
(3) 3-(indol-3-yl)acryloyl-CoA + (R)-3-(indol-3-yl)lactate = 3-(indol-3-yl)acrylate + (R)-3-(indol-3-yl)lactoyl-CoA
Other name(s): FldA; cinnamoyl-CoA:phenyllactate CoA-transferase
Systematic name: 3-(aryl)acryloyl-CoA:(R)-3-(aryl)lactate CoA-transferase
Comments: The enzyme, found in some amino acid-fermenting anaerobic bacteria, participates in the fermentation pathways of L-phenylalanine, L-tyrosine, and L-tryptophan. It forms a complex with EC 4.2.1.175, (R)-3-(aryl)lactoyl-CoA dehydratase.
