Toxic component of a type II toxin-antitoxin (TA) system. Ribosome-independent, sequence-specific endoribonuclease that cleaves mRNA, thus inhibiting protein synthesis and inducing bacterial stasis. It cuts between the first and nucleotides of 5'-UACAU-3' in single-stranded RNA. Neutralized by coexpression with cognate antitoxin MazE. MazF Protein, S. epidermidis, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 19.0 kDa and the accession number is Q9F7V5.

ZC3H12A Protein, Human, Recombinant (His) is expressed in E. coli.

Catalyzes the formation of the second messenger cAMP from ATP. Its transcript is probably degraded by endoribonuclease LS (rnlA), decreasing cAMP levels and the negative regulator Crp-cAMP, which then induces its own transcription again.

Heat-Responsive Protein 12 (HRSP12) is an endoribonuclease that belongs to the Rut family. HRSP12 is found mainly in the human adult kidney and liver and is responsible for inhibiting protein translation by cleaving mRNA. HRSP12 only cleaves phosphodiester bonds in single-stranded RNA and inhibits cell-free protein synthesis. The levels of both mRNA and protein are markedly reduced in heptatocellular tumors and in human hepatoma cell lines compared with normal liver tissues. Moreover the levels of HRSP12 are different depending on the grade of the tumor. This had led to the suggestion that HRSP12 may be an important biomarker for heptatic carcinoma.

Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. Controls, positively or negatively, the expression of several hundred genes, which are mainly involved in metabolism, transport, regulation and stress management.; Protects stationary phase cells from killing induced by endoribonuclease MazF.
