Function Uniprot | Toxic component of a toxin-antitoxin (TA) module. Has RNase activity and preferentially cleaves at the 3'-end of purine ribonucleotides (By similarity). Overexpression in M.tuberculosis or M.smegmatis inhibits colony formation in a bacteriostatic rather than bacteriocidal fashion. Its toxic effect is neutralized by coexpression with cognate antitoxin RelB2 (shown only for M.smegmatis). Overexpression also increases the number of gentamicin-tolerant and levofloxacin-tolerant persister cells. |
