Protein existenceInferred from homology

General annotation (Comments)

Function

Phototransformation of protochlorophyllide (Pchlide) to chlorophyllide (Chlide).

Catalytic activity

Chlorophyllide a + NADP+ = protochlorophyllide + NADPH.

Pathway

Porphyrin-containing compound metabolism; chlorophyll biosynthesis.

Sequence similarities

Belongs to the short-chain dehydrogenases/reductases (SDR) family. POR subfamily.

Sequence caution

The sequence AAA68281.1 differs from that shown. Reason: Erroneous initiation.
