| Other name(s): |
NADPH2-protochlorophyllide oxidoreductase; NADPH-protochlorophyllide oxidoreductase; NADPH-protochlorophyllide reductase; protochlorophyllide oxidoreductase (ambiguous); protochlorophyllide photooxidoreductase; light-dependent protochlorophyllide reductase |
| Systematic name: |
chlorophyllide-a:NADP+ 7,8-oxidoreductase |
| Comments: |
The enzyme catalyses a light-dependent trans-reduction of the D-ring of protochlorophyllide; the product has the (7S,8S)-configuration. |
