Function
function
Catalyzes the release of L-lysine from [LysW]-gamma-L-lysine and the release of L-ornithine from [LysW]-L-ornithine.
Catalytic activity
- [amino-group carrier protein]-C-terminal-gamma-(L-lysyl)-L-glutamate + H2O = [amino-group carrier protein]-C-terminal-L-glutamate + L-lysine
Cofactor
Co2+ (UniProtKB | Rhea| CHEBI:48828 )
Note: Binds 2 Zn2+ or Co2+ ions per subunit.
Pathway
Amino-acid biosynthesis; L-lysine biosynthesis via AAA pathway; L-lysine from L-alpha-aminoadipate (Thermus route): step 5/5.
Amino-acid biosynthesis; L-arginine biosynthesis.
