3.3.2.15 | (5S,6S)-6-amino-5-[(1-carboxyethenyl)oxy]cyclohexa-1,3-diene-1-carboxylate + H2O = (5S,6S)-6-amino-5-hydroxycyclohexa-1,3-diene-1-carboxylic acid + pyruvate |
mechanism in which the carboxylate acts as a general acid to protonate the substrate, yielding a carbocation/oxocarbonium ion that is then rapidly hydrated to form a hemiketal intermediate, which then decomposes spontaneously to products |
