DUF619 domain of N-acetylglutamate Synthase of the fungal arginine-biosynthetic pathway
DUF619-NAGS-FABP: This family includes the DUF619 domain of N-acetylglutamate synthase (NAGS) of the fungal arginine-biosynthetic pathway (FABP). This NAGS (also known as arginine-requiring protein 2 or ARG2) consists of an N-terminal NAG kinase-like domain and a C-terminal DUF619 domain. NAGS catalyzes the formation of NAG from acetylcoenzyme A and L-glutamate. The DUF619 domain, yet to be characterized, is predicted to function in NAGS association in fungi.
