ENZYME entry: EC 1.1.1.3

Accepted Name
homoserine dehydrogenase.
Reaction catalysed
  • L-homoserine + NAD(+) <=> H(+) + L-aspartate 4-semialdehyde + NADH
  • L-homoserine + NADP(+) <=> H(+) + L-aspartate 4-semialdehyde + NADPH
Comment(s)
  • The enzyme from Saccharomyces cerevisiae acts most rapidly with NAD(+); the Neurospora enzyme with NADP(+).
  • The enzyme from Escherichia coli is a multifunctional protein, which also catalyzes the reaction of EC 2.7.2.4.
