Protein
Erythromycin C-12 hydroxylase
Organism
Saccharopolyspora erythraea (strain ATCC 11635 / DSM 40517 / JCM 4748 / NBRC 13426 / NCIMB 8594 / NRRL 2338)
Function
Responsible for the C-12 hydroxylation of the macrolactone ring of erythromycin. Thus, EryK catalyzes the hydroxylation of erythromycin D (ErD) at the C-12 position to produce erythromycin C (ErC). Erythromycin B (ErB) is not a substrate for this enzyme.
Similarity
Belongs to the cytochrome P450 family.
