Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the interconversion of L-alanine and D-alanine. May also act on other amino acids.UniRule annotation

Catalytic activityi

L-alanine = D-alanine.UniRule annotation

Cofactori

pyridoxal 5'-phosphateUniRule annotation

Pathwayi: D-alanine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes D-alanine from L-alanine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Alanine racemase 1 (alr1), Alanine racemase 2 (alr2)
This subpathway is part of the pathway D-alanine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-alanine from L-alanine, the pathway D-alanine biosynthesis and in Amino-acid biosynthesis.
