• Function: This enzyme is a P-450 heme-thiolate protein, and it catalyzes C-C bond formation between the carbons ortho to the phenolic hydroxyl of cyclo(L-tyr-L-tyr) (cYY) producing mycocyclosin. The enzme also can use cyclo(L-Tyr-L-Phe) (cYF), cyclo(L-Tyr-L-Trp) (cYW) and cyclo(L-Tyr-L-3,4-dihydroxyphenylalanine) (cY-DOPA) as substrate.
