Putative copG family helix-turn-helix protein; Similar to E. coli negative regulator of translation (AAC74637.1); Blastp hit to AAC74637.1 (79 aa), 46% identity in aa 1 - 79.

Putative DNA-damage-inducibile protein; Resembles dinJ; similar to E. coli damage-inducible protein J (AAC73330.1); Blastp hit to AAC73330.1 (86 aa), 83% identity in aa 1 - 86.

Putative translation initiation inhibitor; Similar to E. coli orf, hypothetical protein (AAC77205.1); Blastp hit to AAC77205.1 (131 aa), 82% identity in aa 1 - 129.

Putative nucleic acid-binding protein; Toxic component of a type II toxin-antitoxin (TA) system. A site-specific tRNA-(fMet) endonuclease, it cleaves both charged and uncharged tRNA-(fMet) between positions 38 and 39 at the anticodon stem-loop boundary. Does not cleave tRNA(Met), tRNA(Arg2), tRNA(His), tRNA(Leu), tRNA(Phe) tRNA(Thr1), tRNA(Tyr) or tRNA(Val). Overexpression in E.coli inhibits translation, leads to loss of cell growth and degradation of tRNA(fMet), these effects are neutralized by expression of cognate antitoxin VapB. Expression also activates translation initiation at c [...]

Putative helix-turn-helix protein.

Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC76117.1); Blastp hit to AAC76117.1 (138 aa), 45% identity in aa 19 - 138.

Putative cytoplasmic protein; Putative antitoxin component of a toxin-antitoxin (TA) system; its cognate toxin is unknown.

Putative ABC superfamily (atp&memb) transport protein; Part of the tripartite efflux system MacAB-TolC. MacB is a non-canonical ABC transporter that contains transmembrane domains (TMD), which form a pore in the inner membrane, and an ATP-binding domain (NBD), which is responsible for energy generation. Confers resistance against macrolides.
