Cytochrome P450, family 107, also known as CYP107, is a cytochrome P450 monooxygenase family in bacteria, [2] [1] found to be conserved and highly populated in Streptomyces and Bacillus species. [3] The first gene identified in this family is Cytochrome P450 eryF (CYP107A1) from Saccharopolyspora erythraea . [4] Many enzymes of this family are involved in the synthesis of macrolide antibiotics. [2] [5] The members of this family are widely distributed in Alphaproteobacteria, cyanobacterial, Mycobacterium , Bacillota, and Streptomyces species, which may be due to horizontal gene transfer driven by selection pressure.
