WebJul 3, 2024 · The secondary structure of T. cruzi RNA triphosphatase (TcCet1) is shown above the amino acid sequence. TcCet1 amino acids shaded in blue correspond to the segments that are removed in TcCet1 (18–243 Δ55–75) protein. WebThe cap is then methylated at the guanine N7 position by RNA (guanine-7) methyltransferase, completing the m 7 GpppN, or cap0, structure (for review, see Mizumoto and Kaziro 1987; Shuman 1995). In higher eukaryotes, a bifunctional monomeric polypeptide carries both RNA triphosphatase and guanylyltransferase activities ( Mizumoto and …

WebThe systematic name is polynucleotide 5′-phosphohydrolase. This enzyme is also called 5′-polynucleotidase . The only specific molecular function known is the catalysis of the reaction: a 5′-end triphospho- (purine-ribonucleotide) in mRNA + H 2 O = a 5′-end diphospho- (purine-ribonucleoside) in mRNA + phosphate WebDec 7, 2001 · The triphosphatase TbCet1 is a member of a new family of metal-dependent phosphohydrolases that includes the RNA triphosphatases of fungi and the malaria parasite Plasmodium falciparum. The protozoal/fungal enzymes are structurally and mechanistically unrelated to the RNA triphosphatases of metazoans and plants.
WebLack of a high-resolution structure made it difficult to elucidate 2C activity and prevented inhibitor development. We report the 2.5 Å–resolution crystal structure of the soluble part of EV71 2C, containing an adenosine triphosphatase (ATPase) domain, a cysteine-rich zinc finger with an unusual fold, and a carboxyl-terminal helical domain. WebJun 1, 2001 · It shares the same core structure as other currently available proton-pump inhibitors (PPIs). The FDA-labeled indication is the short-term treatment of erosive esophagitis. PPIs act by selectively inhibiting H+/K(+)-ATPase in the secretory canaliculus of the stimulated parietal cell.
