Function

[Q72EC8_DESVH] Catalyzes the insertion of Co(2+) into sirohydrochlorin. To a lesser extent, is also able to insert Fe(2+) into sirohydrochlorin, yielding siroheme. Its periplasmic location means that it cannot participate in cobalamin biosynthesis and its genomic environment suggests it is likely to be associated with a heme or metal transport system.
