Biol. Chem. 281:2893-2900(2006). CC -!- FUNCTION: This protein promotes the GTP-dependent binding of CC aminoacyl-tRNA to the A-site of ribosomes during protein CC biosynthesis. CC -!- FUNCTION: May play an important regulatory role in cell growth and CC in the bacterial response to nutrient deprivation. CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00118, CC ECO:0000269|PubMed:8596629, ECO:0000269|PubMed:8939740}. CC -!- SUBCELLULAR LOCATION: Cytoplasm. Cell inner membrane; Peripheral CC membrane protein. Note=Between 50-80% of the protein is associated CC with the cell inner membrane. Localization to the membrane has CC been suggested to follow nutrient stress. CC -!- PTM: The N-terminus is blocked. CC -!- PTM: Methylated in vivo on Lys-57 in response to nutrient CC starvation. {ECO:0000269|PubMed:2022614, CC ECO:0000269|PubMed:389663, ECO:0000269|PubMed:6997043, CC ECO:0000269|PubMed:7021545}. CC -!- PTM: Phosphorylated in vitro by phage protein doc on Thr-383. CC {ECO:0000269|PubMed:19150849, ECO:0000269|PubMed:24141193, CC ECO:0000269|PubMed:8416965}. CC -!- PTM: Phosphorylated in vitro by HipA on Thr-383 (PubMed:19150849), CC this has since been reported not to occur in vivo CC (PubMed:24095282). {ECO:0000269|PubMed:19150849, CC ECO:0000269|PubMed:24095282, ECO:0000269|PubMed:24141193, CC ECO:0000269|PubMed:8416965}. CC -!- MISCELLANEOUS: This chain is also used in bacteriophage Q-beta RNA CC polymerase. CC -!- MISCELLANEOUS: Present with about 70,000 molecules/cell. CC {ECO:0000305|PubMed:775340}. CC -!- MISCELLANEOUS: The antibiotic kirromycin inhibits protein CC biosynthesis by inhibiting the release of EF-Tu from the ribosome. CC TufA resistance to kirromycin is conferred by mutations to Gln- CC 125, Gly-317 and Ala-376. This has not been formally proven for CC tufB, but is certainly correct. CC -!- MISCELLANEOUS: The antibiotic pulvomycin inhibits protein CC biosynthesis by disrupting the allosteric control mechanism of EF- CC Tu TufA resistance to pulvomycin is conferred by Arg-231, Arg-334 CC and Thr-335. This has not been formally proven for tufB, but is CC certainly correct. CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase CC superfamily. Classic translation factor GTPase family. EF-Tu/EF-1A CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00118}. CC -!- SIMILARITY: Contains 1 tr-type G (guanine nucleotide-binding) CC domain. {ECO:0000305}. CC -!- CAUTION: EF-Tu 1 and EF-Tu 2 differ in a single position and are CC no longer merged. However, many papers are found in both entries CC as it is not always possible to determine for each paper which of CC EF-Tu 1 or EF-Tu 2 was being worked upon. {ECO:0000305}.
