Accepted name: [amino group carrier protein]-ornithine hydrolase
Reaction: [amino group carrier protein]-C-terminal-γ-(L-ornithyl)-L-glutamate + H2O = [amino group carrier protein]-C-terminal-L-glutamate + L-ornithine
Other name(s): lysK (gene name)
Systematic name: [amino group carrier protein]-C-terminal-γ-L-ornithyl-L-glutamate amidohydrolase
Comments: The enzyme participates in an L-arginine biosynthetic pathways in certain species of archaea and bacteria. In all cases known so far the enzyme also catalyses the activity of EC, [amino group carrier protein]-lysine hydrolase.
