This domain is found in monooxygenases involved in the biosynthesis of several antibiotics by Streptomyces species. It's occurrence as a repeat in Streptomyces coelicolor SCO1909 (Swiss:Q9X9W3) is suggestive that the other proteins function as multimers. There is also a conserved histidine which is likely to be an active site residue.	Domain
