Analysis of rILERS, an isoleucyl-tRNA synthetase gene associated with mupirocin production by Pseudomonas fluorescens NCIMB 10586. (2002)

Rangaswamy, V., Hernandez-Guzman, G., Shufran, K. A, Bender, C. L

Some strains of Pseudomonas fluorescens produce the antibiotic mupirocin, which functions as a competitive inhibitor of isoleucyl-tRNA synthetase (ILERS). Mupirocin-producing strains of P....
