Reaction: tauropine + NAD+ + H2O = taurine + pyruvate + NADH + H+
Systematic name: N2-(D-1-carboxyethyl)taurine:NAD+ oxidoreductase (taurine-forming)
Comments: In the reverse reaction, alanine can act instead of taurine, but more slowly, and 2-oxobutanoate and 2-oxopentanoate can act instead of pyruvate.
