protein-synthesizing GTPase (elongation factor Tu) M-CSA #535 | Elongation factor Tu hydrolyses GTP to give GDP and Pi, thus providing the free energy that the ribosome needs to incorporate amino acids into the growing polypeptide. As such, it shows homology to other GTP binding proteins such as the oncogene ras, but may show a different mechanism of GTP hydrolysis. Many antibiotics are able to inhibit EFTu, making study of its mechanism particularly useful in view of the possibility of synthesising new antibiotics. | Defined by 4 residues: ASP:A-22 [auth A-21]LYS:A-25 [auth A-24]THR:A-26 [auth A-25]HIS:A-85 [auth A-84] | |
