7-Hydroxymethyl chlorophyll a reductase

7-Hydroxymethyl chlorophyll a reductase (, HCAR) is an enzyme with systematic name 71-hydroxychlorophyll a:ferredoxin oxidoreductase. This enzyme catalyses the following chemical reaction


 * 71-hydroxychlorophyll a + 2 reduced ferredoxin + 2 H+ $$\rightleftharpoons$$ chlorophyll a + 2 oxidized ferredoxin + H2O

7-Hydroxymethyl chlorophyll is a reductase that contains FAD and an iron-sulfur center.
