In molecular biology, members of the ArgJ protein family are bifunctional protein that catalyses the first (EC and fifth steps (EC in arginine biosynthesis.[1] The structure has been determined for glutamate N-acetyltransferase 2 (ornithine acetyltransferase), an ArgJ-like protein from Streptomyces clavuligerus.[2]
