3.A.1.5.21
The Microcin C/peptide uptake porter, YejABEF (Novikova et al., 2007).  The 'Trojan horse' antibiotic, microcin C, consists of a nonhydrolyzable aspartyl-adenylate that is efficiently imported into bacterial cells owing to a covalently attached peptide. Once inside the cell, the peptide "carrier" is removed by proteolytic processing to release a potent aspartyl tRNA synthetase inhibitor (Severinov and Nair 2012).
