Enzyme Information

6.3.2.43

[Amino group carrier protein]--L-2-aminoadipate ligase.

based on mapping to UniProt Q5SH23

ATP + [amino group carrier protein]-C-terminal-L-glutamate + L-2- aminoadipate = ADP + phosphate + [amino group carrier protein]-C- terminal-gamma-(L-2-aminoadip-2-yl)-L-glutamate.

-!- 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. -!- Formerly EC 6.3.2.n4.
