Protein
Ornithine racemase
Organism
Acetoanaerobium sticklandii (strain ATCC 12662 / DSM 519 / JCM 1433 / NCIMB 10654)
Function
Involved in the ornithine fermentation pathway. Catalyzes the conversion of L-ornithine to D-ornithine (PubMed:19251850, PubMed:10715017). OR could also racemize basic amino acids such as lysine and arginine (PubMed:19251850). Serine, asparagine and alanine could be also converted by OR, but at a lower rate (PubMed:19251850).
Similarity
Belongs to the alanine racemase family.
