CC   -!- FUNCTION: Part of the bacABCDEFG operon responsible for the
CC       biosynthesis of bacilysin, an irreversible inactivator of the
CC       glutaminase domain of glucosamine synthetase. Catalyzes the
CC       dehydrogenation of the C7-hydroxyl group in the 4S-tetrahydrotyrosine
CC       (4S-H4Tyr) to yield anticapsin (epoxycyclohexanonyl-Ala).
CC       {ECO:0000250|UniProtKB:P39640}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-dihydroanticapsin + NAD(+) = H(+) + L-anticapsin + NADH;

CC         EC=1.1.1.385; Evidence={ECO:0000250|UniProtKB:P39640};
CC   -!- PATHWAY: Antibiotic biosynthesis; bacilysin biosynthesis.
CC       {ECO:0000305|PubMed:15609023}.
CC   -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC       family. {ECO:0000305}.
