Research Abstract |
We identified 7-hydroxymethyl chlorophyll a reductase (HCAR). Recombinant HCAR converted 7hydroxymethyl chlorophyll a to chlorophyll a by using ferredoxin and contains FAD and an iron-sulfur center. A phylogenetic analysis elucidated the evolution of 7-hydroxymethyl chlorophyll a reductase from divinyl chlorophyllide vinyl reductase. We examined the substrate specificity of HCAR and determined the chlorophyll b degradation pathway in which chlorophyll b is converted to chlorophyll a via 7-hydroxymethyl chlorophyll a.
