- precorrin-6B + NADP+ [math]\rightleftharpoons[/math] precorrin-6A + NADPH + H+
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is precorrin-6B:NADP+ oxidoreductase. Other names in common use include precorrin-6X reductase, and precorrin-6Y:NADP+ oxidoreductase. This enzyme participates in porphyrin and chlorophyll metabolism.
