Function

[EFTU1_ECOLI] This protein promotes the GTP-dependent binding of aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis.[HAMAP-Rule:MF_00118] May play an important regulatory role in cell growth and in the bacterial response to nutrient deprivation.[HAMAP-Rule:MF_00118] [THCL_PLARO] Has bacteriocidal activity against Gram-positive bacteria and a few Gram-negative bacteria. It is particularly active against anaerobes. Inhibits bacterial protein biosynthesis by preventing the formation of a stable complex between the elongation factor Tu (EF-Tu), GTP and tRNA, hindering the activation of EF-Tu.

Publication Abstract from PubMed

4-Aminothiazolyl analogues of the antibiotic natural product GE2270 A (1) were designed, synthesized, and optimized for their activity against Gram positive bacterial infections. Optimization efforts focused on improving the physicochemical properties (e.g., aqueous solubility and chemical stability) of the 4-aminothiazolyl natural product template while improving the in vitro and in vivo antibacterial activity. Structure-activity relationships were defined, and the solubility and efficacy profiles were improved over those of previous analogues and 1. These studies identified novel, potent, soluble, and efficacious elongation factor-Tu inhibitors, which bear cycloalkylcarboxylic acid side chains, and culminated in the selection of development candidates amide 48 and urethane 58.
