Protein Family Models

Radical SAM proteins catalyse diverse reactions, including unusual methylations, isomerisation, sulphur insertion, ring formation, anaerobic oxidation and protein radical formation. [1]. 11222759.

Members of this radical SAM protein family are HemZ, a protein involved in coproporphyrinogen III decarboxylation. Alternative names for this enzyme (EC 1.3.99.22) include coproporphyrinogen dehydrogenase and oxygen-independent coproporphyrinogen III oxidase. The family is related to, but distinct from HemN, and in Bacillus subtilis was shown to be connected to peroxide stress and catalase formation.

coproporphyrinogen III oxidase family protein is a radical SAM protein similar to Bacillus subtilis oxygen-independent coproporphyrinogen-III oxidase-like protein HemZ, which is involved in the biosynthesis of porphyrin-containing compounds
