[[http://www.uniprot.org/uniprot/CP121_MYCTO CP121_MYCTO]] Catalyzes C-C bond formation between the carbons ortho to the phenolic hydroxyl of cyclo(L-tyr-L-tyr) (cYY) producing mycocyclosin. Can also 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 (By similarity).

== Publication Abstract from PubMed ==
 +
A series of analogues of cyclo(l-tyrosyl-l-tyrosine), the substrate of the Mycobacterium tuberculosis enzyme CYP121, have been synthesized and analyzed by UV-vis and electron paramagnetic resonance spectroscopy and by X-ray crystallography. The introduction of iodine substituents onto cyclo(l-tyrosyl-l-tyrosine) results in sub-muM binding affinity for the CYP121 enzyme and a complete shift to the high-spin state of the heme Fe(III). The introduction of halogens that are able to interact with heme groups is thus a feasible approach to the development of next-generation, tight binding inhibitors of the CYP121 enzyme, in the search for novel antitubercular compounds.
