higA | Hypothetical protein ygjM; Antitoxin component of a type II toxin-antitoxin (TA) system. Functions as an mRNA interferase antitoxin. (138 aa) | ||||
cbtA | Hypothetical protein yeeV; Toxic component of a type IV toxin-antitoxin (TA) system. Acts as a dual toxin inhibitor that blocks cell division and cell elongation in genetically separable interactions with FtsZ and MreB. Toxic effects are neutralized by cognate antitoxin CbeA (A0A0H2V8S8), although there is no direct interaction detected between the 2 proteins. (124 aa) | ||||
yoeB | Hypothetical protein; Toxic component of a type II toxin-antitoxin (TA) system. It has been proposed to be an mRNA interferase but also an inhibitor of translation initiation. Has an in vitro RNase activity and preferentially cleaves at the 3'-end of purine ribonucleotides. YefM binds to the promoter region of the yefM-yeoB operon to repress transcription, YeoB acts as a corepressor (By similarity). (84 aa) | ||||
yefM | Hypothetical protein yefM; Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that counteracts the effect of the YoeB mRNA interferase. YefM binds to the promoter region of the yefM-yeoB operon to repress transcription, YeoB acts as a corepressor (By similarity). (92 aa) | ||||
higB | Hypothetical protein; Toxic component of a type II toxin-antitoxin (TA) system. A probable translation-dependent mRNA interferase. Probably counteracted by antitoxin HigA. (103 aa) | ||||
tyrR | Transcriptional Regulatory protein tyrR; Escherichia coli K-12 ortholog: b1323; Escherichia coli O157:H7 ortholog: z2454. (522 aa) |
