[amino group carrier protein]-C-terminal-L-glutamate:L-2-aminoadipate ligase (ADP-forming)
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.

mutant enzyme N264G/T265T shows a substrate preference for glutamate over L-2-aminoadipate contrasting distinctly with the substrate specificity of wild-type enzyme, which shows a distinct preference for L-2-aminoadipate over glutamate

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

no growth of deletion mutant without L-lysine. Growth is possible with lysine supplementation. A 0.05-mM concentration of lysine is most effective to support the growth of the deletion mutant, but a higher concentration of lysine decreases the growth rate

Thermococcus kodakarensis has the potential to biosynthesize lysine and ornithine using the carrier protein LysW-mediated system with a single set of bifunctional enzymes
in the presence of antimicrobial peptides produced by epithelial cells and macrophages, lysX expression increases significantly. Strains with higher lysX expression show increased levels of intracellular survival in vivo and in vitro and induce more severe lesion related with pneumonia. The ability of Mycobacterium tuberculosis to replicate intracellularly is directly correlated to the level of lysX expression; in the presence of antimicrobial peptides produced by epithelial cells and macrophages, lysX expression increases significantly.
