EC 1.14.21.9     
Accepted name: mycocyclosin synthase
Reaction: cyclo(L-tyrosyl-L-tyrosyl) + NADPH + H+ + O2 = mycocyclosin + NADP+ + 2 H2O
Glossary: mycocyclosin = (1S,14S)-6,9-dihydroxy-15,17-diazatetracyclo[12.2.2.13,7.18,12]icosa-3(20),4,6,8(19),9,11-hexaene-16,18-dione
Other name(s): CYP121; rv2276 (gene name)
Systematic name: cyclo(L-tyrosyl-L-tyrosyl),NADPH:oxygen oxidoreductase (diarylbridge-forming)
Comments: A heme-thiolate (P-450) enzyme from the bacterium Mycobacterium tuberculosis catalysing an oxidative reaction that does not incorporate oxygen into the product.
