N(omega)-hydroxy-L-arginine amidinohydrolase
Organism
Streptomyces lavendulae
Function
Involved in the biosynthesis of the antibiotic D-cycloserine (DCS), a cyclic structural analog of D-alanine, used as an antitubercular agent. Catalyzes the hydrolysis of N(omega)-hydroxy-L-arginine (NHA) to yield hydroxyurea (HU) and L-ornithine.
Similarity
Belongs to the arginase family.
