show Brenda entry

EC number

1.5.1.24

Accepted name

N⁵-(carboxyethyl)ornithine synthase

Reaction

N⁵-(L-1-carboxyethyl)-L-ornithine + NADP⁺ + H₂O = L-ornithine + pyruvate + NADPH + H⁺

Other name(s)

5-N-(L-1-carboxyethyl)-L-ornithine:NADP⁺ oxidoreductase (L-ornithine-forming)

Systematic name

N⁵-(L-1-carboxyethyl)-L-ornithine:NADP⁺ oxidoreductase (L-ornithine-forming)

CAS registry number

129070-70-8

Comment

In the reverse direction, L-lysine can act instead of L-ornithine, but more slowly. Acts on the amino group. cf. EC 1.5.1.16, D-lysopine dehydrogenase.
