EC 6.3.2.43     
Accepted name: [lysine-biosynthesis-protein LysW]—L-2-aminoadipate ligase
Reaction: ATP + [lysine-biosynthesis-protein LysW]-C-terminal-L-glutamate + L-2-aminoadipate = ADP + phosphate + [lysine-biosynthesis-protein LysW]-C-terminal-γ-(L-2-aminoadip-2-yl)-L-glutamate
Other name(s): α-aminoadipate-lysW ligase lysX (gene name); LysX (ambiguous); AAA—LysW ligase
Systematic name: [lysine-biosynthesis-protein LysW]-C-terminal-L-glutamate:L-2-aminoadipate ligase (ADP-forming)
Comments: The enzymes from the thermophilic bacterium Thermus thermophilus and the thermophilic archaea Sulfolobus acidocaldarius and Sulfolobus tokodaii protect the amino group of L-2-aminoadipate by conjugation to the carrier protein LysW. This reaction is part of the lysine biosynthesis pathway in these organisms.
