EC 3.5.1.130

Accepted name: [lysine-biosynthesis-protein LysW]-lysine/ornithine hydrolase

Reaction: (1) [lysine-biosynthesis-protein LysW]-C-terminal-γ-(L-ornithyl)-L-glutamate + H2O = [lysine-biosynthesis-protein LysW]-C-terminal-L-glutamate + L-ornithine
(2) [lysine-biosynthesis-protein LysW]-C-terminal-γ-(L-lysyl)-L-glutamate + H2O = [lysine-biosynthesis-protein LysW]-C-terminal-L-glutamate + L-lysine

Other name(s): lysK (gene name)

Systematic name: [lysine-biosynthesis-protein LysW]-C-terminal-γ-(L-ornithyl/L-lysyl)-L-glutamate amidohydrolase

Comments: The enzyme participates in L-arginine and L-lysine biosynthetic pathways in certain species of archaea and bacteria. In some organisms the enzyme also catalyses the activity of EC 3.5.1.132, [amino group carrier protein]-ornithine hydrolase.
