The VS ribozyme catalyses the site-specific cleavage of a phosphodiester linkage by a transesterification reaction that entails the attack of the neighbouring 2'-oxygen with departure of the 5'-oxygen. We have previously suggested that the A730 loop is an important component of the active site of
DNA Photolyase is a flavoprotein that uses light to repair cyclobutylpyrimidine dimers in DNA. From considerations of the crystal structure of the protein, it has been hypothesized that the dimer lesion is flipped out of the DNA double helix into the substrate binding pocket. We have used a
A 6-aminopurine (adenine) derivative of bis(2,2'-bithienyl)methane, vis., 4-[2-(6-amino-9H-purin-9-yl)ethoxy]phenyl-4-[bis(2,2'-bithienyl)methane] or Ade-BTM, was designed and synthesized for recognition of 5-fluorouracil (FU), an antitumor chemotherapy agent, by RNA-type (nucleobase pairing)-driven
Objective: To observe the effects of 2-aminopurine (2-AP), a double-stranded RNA-dependent protein kinase (PKR) inhibitor, on organ function, plasma inflammatory factor expression and 7 days mortality in sepsis mice induced by cecal ligation puncture (CLP). Methods: Forty specific
