Q8VUS5

for the conversion of alpha-aminoadipate to lysine, the amino group of alpha-aminoadipate is modified by attachment to the gamma-carboxyl group of the C-terminal Glu54 of a small protein, LysW. The side chain of alpha-aminoadipate is converted to the lysyl side chain while still attached to LysW, and lysine is subsequently liberated from the LysW-lysine fusion

LysK in complex with lysine at a resolution of 2.4 A. The alpha-amino group of the bound lysine is oriented toward the catalytic center, which is composed of the residues coordinating divalent metal ions for the hydrolysis of the isopeptide bond. An 11 A long path leads from the active site binding lysine to the protein surface. A positively-charged surface region is located around the exit of the path
