Protein attributes

Sequence length	580 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	N-acetylglutamate synthase involved in arginine biosynthesis By similarity.
Catalytic activity	Acetyl-CoA + L-glutamate = CoA + N-acetyl-L-glutamate.
Pathway	Amino-acid biosynthesis; L-arginine biosynthesis; N(2)-acetyl-L-ornithine from L-glutamate: step 1/4.
Subcellular location	Mitochondrion By similarity.
Induction	Up-regulated in cells treated with farnesol and grown at high cell density in N-acetyl-D-glucosamine medium. Expression is regulated by the general amino acid control response transcription factor GCN4. Ref.2
Sequence similarities	Belongs to the acetyltransferase family. Contains 1 N-acetyltransferase domain.
