Description Alanine racemase (family a)
Notes A family that includes mostly bacterial enzymes; exceptions are represented by two sequences from S. pombe and one from a prawn.

The Salmonella enzyme (ALR1) has a monomeric structure.

The enzymes from enterococci (VanT-type) have an additional, N-terminal domain that is membrane-bound and assigned to the acyl-transferase family 3 (PF01757) by Pfam. This additional domain should be removed from the sequences in quesion.

Additional_domain AAD22403.1 300-700

PLP Fold Type III
PLP-dependent Domain
Domain alignment
Domain hmm
Fold type III

Reference sequence ALR_BACST
Domain interval 7-230
