Sirohaem biosynthesis protein central
This is the central domain of a multifunctional enzyme which catalyzes the biosynthesis of sirohaem. Both of the catalytic activities of this enzyme (precorrin-2 dehydrogenase EC:1.3.1.76) and sirohydrochlorin ferrochelatase (EC:4.99.1.4) are located in the N-terminal domain of this enzyme, pfam13241.
