6.3.2.43 ATP + [LysW]-C-terminal-L-glutamate54 + L-2-aminoadipate Thermus thermophilus the enzyme is involved in biosynthesis of lysine. LysX activates the gamma-carboxyl group of the C-terminal Glu54 of the 2-L-aminoaadipate carrier-protein LysW by phosphorylation, with concomitant conversion of ATP to ADP. LysX recognizes not only the C-terminal glutamate residue of LysW but also other portions, possibly the globular domain of LysW specifically ADP + phosphate + [LysW]-C-terminal-gamma-(L-2-aminoadip-2-yl)-L-glutamate54
