Post-translational modificationi

Formation of an isopeptide bond between the gamma-carboxyl group of the C-terminal glutamate and the amino group of alpha-aminoadipate (AAA) is catalyzed by LysX. The bound AAA is then converted to L-lysine in a series of reactions catalyzed by LysZ, LysY and LysJ. Release of the product L-lysine is catalyzed by LysK. Formation of an isopeptide bond between the gamma-carboxyl group of the C-terminal glutamate and the amino group of L-glutamate is catalyzed by ArgX. The bound substrate is then sequentially converted to ornithine which is eventually converted to L-arginine (PubMed:23434852).1 Publication
