Reaction: an [amino-group carrier protein]-C-terminal-[γ-(L-ornithyl)-L-glutamate] + 2-oxoglutarate = an [amino-group carrier protein]-C-terminal-[γ-(L-glutamate 5-semialdehyde-2-yl)-L-glutamate] + L-glutamate
Other name(s): lysJ (gene name)
Systematic name: 2-oxoglutarate:[amino-group carrier protein]-C-terminal-[γ-(L-ornithyl)-L-glutamate] aminotransferase
Comments: The enzyme participates in an L-arginine biosynthetic pathway that operates in certain species of archaea. In some cases the enzyme also catalyses the activity of EC 2.6.1.118, [amino-group carrier protein]-γ-(L-lysyl)-L-glutamate aminotransferase.
