text: The modification required to biosynthesize mature chloroeremomycin include: oxidative cross-linking of aromatic rings, hydroxylation and chlorination of the two Tyr residues, methylation of Leu, and glycosylation at aa4 and aa6.
  The oxidative crosslinks are catalyzed by enzymes OxyA-C. The glycosylations are catalyzed by enzymes GtfA-C (coded by Orf11-13 respectively). The chlorinations are performed by enzymes encoded by Orf10 and 18.
