Miscellaneous

This chain is also used in bacteriophage Q-beta RNA polymerase.
Present with about 70,000 molecules/cell (1 Publication).
The antibiotic kirromycin inhibits protein biosynthesis by inhibiting the release of EF-Tu from the ribosome. TufA resistance to kirromycin is conferred by mutations to Gln-125, Gly-317 and Ala-376. This has not been formally proven for tufB, but is certainly correct.
The antibiotic pulvomycin inhibits protein biosynthesis by disrupting the allosteric control mechanism of EF-Tu TufA resistance to pulvomycin is conferred by Arg-231, Arg-334 and Thr-335. This has not been formally proven for tufB, but is certainly correct.

Caution

EF-Tu 1 and EF-Tu 2 differ in a single position and are no longer merged. However, many papers are found in both entries as it is not always possible to determine for each paper which of EF-Tu 1 or EF-Tu 2 was being worked upon.
