4CH7, 4CZC - PubMed Abstract: 
The isobacteriochlorin heme d1 serves as an essential cofactor in the cytochrome cd1 nitrite reductase NirS that plays an important role for denitrification. During the biosynthesis of heme d1, the enzyme siroheme decarboxylase catalyzes the conversion of siroheme to 12,18-didecarboxysiroheme ...
