ENZYME - 1.2.1.95 L-2-aminoadipate reductase

Accepted Name
L-2-aminoadipate reductase
Alternative Name(s)
alpha-aminoadipate reductase
Reaction catalysed
(S)-2-amino-6-oxohexanoate + AMP + diphosphate + NADP(+) = L-2-aminoadipate + ATP + NADPH + H(+)
Comment(s)
  • This enzyme, characterized from the yeast Saccharomyces cerevisiae, catalyzes the reduction of L-2-aminoadipate to (S)-2-amino-6- oxohexanoate during L-lysine biosynthesis.
  • An adenylation domain activates the substrate at the expense of ATP hydrolysis, and forms L-2-aminoadipate adenylate, which is attached to a peptidyl-carrier protein (PCP) domain.
  • Binding of NADPH results in reductive cleavage of the acyl-S-enzyme intermediate, releasing (S)-2-amino-6-oxohexanoate.
  • Different from EC 1.2.1.31 which catalyzes a similar transformation in the opposite direction without ATP hydrolysis.
