Heme A synthase, type 1 (IPR023755)

Short name: HemeA_Synthase_type1

Overlapping homologous superfamilies


Family relationships


Heme A synthase catalyzes the oxidation of the C8 methyl side group on heme O porphyrin ring into a formyl group [PMID: 15491161].

The type 1 subfamily of this enzyme is found in Gram-positive bacteria. Bacillus subtilis CatA is involved in sporulation [PMID: 12206660].
