Title: Amino acid residues required for maturation, cell uptake, and processing of translation inhibitor microcin C. Author: Kazakov T, Metlitskaya A, Severinov K. Journal: J Bacteriol; 2007 Mar; 189(5):2114-8. PubMed ID: 17158672. Abstract: Microcin C (McC), a peptide-nucleotide Trojan horse antibiotic, targets aspartyl-tRNA synthetase. We present the results of a systematic mutational study of the 7-amino-acid ribosomally synthesized peptide moiety of McC. Our results define amino acid positions important for McC maturation and cell uptake and processing and open the way for creation of more potent McC-based inhibitors.[Abstract] [Full Text] [Related] [New Search]
