ENTRY       EC 1.5.1.23
NAME        Tauropine dehydrogenase
CLASS       Oxidoreductases
            Acting on the CH-NH group of donors
            With NAD+ or NADP+ as acceptor
SYSNAME     N2-(D-1-Carboxyethyl)taurine:NAD+ oxidoreductase (taurine-forming)
REACTION    Tauropine + NAD+ + H2O = Taurine + Pyruvate + NADH
SUBSTRATE   Tauropine
            NAD+
            H2O
PRODUCT     Taurine
            Pyruvate
            NADH
            2-Oxobutanoate
            2-Oxopentanoate
COMMENT     In the reverse reaction, alanine can act instead of taurine, more
            slowly, and 2-oxobutanoate and 2-oxopentanoate can act instead of
            pyruvate.
