CC by inhibiting the release of EF-Tu from the ribosome. TufA resistance
CC to kirromycin is conferred by mutations to Gln-125, Gly-317 and Ala-
CC 376. This has not been formally proven for tufB, but is certainly
CC correct. {ECO:0000305}.
CC -!- MISCELLANEOUS: The antibiotic pulvomycin inhibits protein biosynthesis
CC by disrupting the allosteric control mechanism of EF-Tu TufA resistance
CC to pulvomycin is conferred by Arg-231, Arg-334 and Thr-335. This has
CC not been formally proven for tufB, but is certainly correct.
CC {ECO:0000305}.
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 -!- CAUTION: EF-Tu 1 and EF-Tu 2 differ in a single position and are no
CC longer merged. However, many papers are found in both entries as it is
CC not always possible to determine for each paper which of EF-Tu 1 or EF-
CC Tu 2 was being worked upon. {ECO:0000305}.
