Functional Family Arginine biosynthesis bifunctional protein ArgJ

Enzyme Information

2.3.1.1
Amino-acid N-acetyltransferase.
based on mapping to UniProt P9WPZ3
Acetyl-CoA + L-glutamate = CoA + N-acetyl-L-glutamate.
-!- Also acts with L-aspartate and, more slowly, with some other amino acids.
2.3.1.35
Glutamate N-acetyltransferase.
based on mapping to UniProt P9WPZ3
N(2)-acetyl-L-ornithine + L-glutamate = L-ornithine + N-acetyl-L- glutamate.
-!- Also has some hydrolytic activity on acetyl-L-ornithine, but the rate is 1% of that of transferase activity.
