- Sirohydrochlorin cobaltochelatase
In
enzymology , a sirohydrochlorin cobaltochelatase (EC number|4.99.1.3) is anenzyme that catalyzes thechemical reaction :cobalt-sirohydrochlorin + 2 H+ sirohydrochlorin + Co2+
Thus, the two substrates of this enzyme are
cobalt-sirohydrochlorin and H+, whereas its two products aresirohydrochlorin andCo2+ .This enzyme belongs to the family of
lyase s, specifically the "catch-all" class of lyases that do not fit into any other sub-class. The systematic name of this enzyme class is cobalt-sirohydrochlorin cobalt-lyase (sirohydrochlorin-forming). Other names in common use include CbiK, CbiX, CbiXS, anaerobic cobalt chelatase, cobaltochelatase [ambiguous] , and sirohydrochlorin cobalt-lyase (incorrect). This enzyme participates inporphyrin and chlorophyll metabolism .tructural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|1TJN and PDB link|2DJ5.
