"description": "DarE catalyzes the ether and C\u2013C crosslinks of DarA precursor peptide into macrocyclized intermediate before cleavage of leader and follower peptide by protease to mature Darobactin. The formation of the ether link between two Trp residues precedes the formation of C\u2013C crosslink of Lys and a Trp in the darobactin biosynthesis.
