Accepted name: |
7-hydroxymethyl chlorophyll a reductase |
Reaction: |

Glossary: |
71-hydroxychlorophyll a = 7-hydroxymethyl-chlorophyll a |
Other name(s): |
HCAR; 71-hydroxychlorophyll-a:ferredoxin oxidoreductase |
Systematic name: |
chlorophyll-a:ferredoxin oxidoreductase |
Comments: |
Contains FAD and an iron-sulfur center. This enzyme, which is present in plant chloroplasts, carries out the second step in the conversion of chlorophyll b to chlorophyll a. It similarly reduces chlorophyllide a. |
