[ | [https://www.uniprot.org/uniprot/VAPC_SHIFL VAPC_SHIFL] Toxic component of a toxin-antitoxin (TA) module. A 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. The VapB/VapC complex probably regulates transcription of its own promoter.<ref>PMID:19400780</ref> <ref>PMID:21502523</ref> Ectopic overexpression in E.coli induces the YoeB toxin, but this is not the cause of VapC toxicity.<ref>PMID:19400780</ref> <ref>PMID:21502523</ref> | ||
