Structural determination of the functional sites of E. coli elongation factor Tu.
Recently, we have made significant progress in solving the structure of a nicked form of elongation factor (EF)-Tu complexed with GDP. The structure has been refined to an R factor of 19.2% at 2.6 A resolution, so that most of the structure is clearly visible in the electron density map. Here we describe what is known about functional sites of EF-Tu in terms of the structure, which still lacks amino acids 40-60.
