CC   -!- FUNCTION: Involved in the biosynthesis of the nonproteinogenic amino
CC       acid monomer (S)-3,5-dihydroxyphenylglycine (Dpg) responsible of the
CC       production of vancomycin and teicoplanin antibiotics. Catalyzes the
CC       syn-addition of a water molecule across the double bond of a trans-2-
CC       enoyl-CoA thioester, resulting in the formation of a beta-hydroxyacyl-
CC       CoA thioester. Physiologically, DpgB could act as a dehydratase,
CC       facilitating the aromatization of the DPA-S-DgpA or DPA-S-CoA
CC       intermediate. {ECO:0000269|PubMed:11752437}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a (3S)-3-hydroxyacyl-CoA = a (2E)-enoyl-CoA + H2O;

CC   -!- PATHWAY: Antibiotic biosynthesis; vancomycin biosynthesis.
CC       {ECO:0000305|PubMed:11752437}.
CC   -!- SIMILARITY: Belongs to the enoyl-CoA hydratase/isomerase family.
