RIBOSOMAL ELONGATION FACTOR G (EF-G) FUSIDIC ACID RESISTANT MUTANT G16V
Overview
Fusidic acid (FA) is a steroid antibiotic commonly used against Gram, positive bacterial infections. It inhibits protein synthesis by stalling, elongation factor G (EF-G) on the ribosome after translocation. A, significant number of the mutations conferring strong FA resistance have, been mapped at the interfaces between domains G, III and V of EF-G., However, direct information on how such mutations affect the structure has, hitherto not been available. Here we present the crystal structures of two, mutants of Thermus thermophilus EF-G, G16V and T84A, which exhibit FA, hypersensitivity and resistance in vitro, respectively. These mutants also, have higher and lower affinity for GTP respectively than wild-type EF-G., The mutations cause significant conformational changes in the switch II, ... [(full description)]
