Holocytochrome-c synthase

From Wikipedia, the free encyclopedia

In enzymology, a holocytochrome-c synthase (EC 4.4.1.17) is an enzyme that catalyzes the chemical reaction

holocytochrome c apocytochrome c + heme

Hence, this enzyme has one substrate, holocytochrome c, and two products, apocytochrome c and heme.

This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is holocytochrome-c apocytochrome-c-lyase (heme-forming). Other names in common use include cytochrome c heme-lyase, holocytochrome c synthetase, and holocytochrome-c apocytochrome-c-lyase. This enzyme participates in porphyrin and chlorophyll metabolism.
