WebDec 25, 2012 · These data suggest that the generation of a consensus recombinase is indeed an efficient way to generate a highly active enzyme from a pool of sequenced clones. During the evolution cycles, little selection pressure is enforced on the specificity of the enzyme. Indeed, target promiscuity has been widely seen in directed evolution … WebMay 12, 2010 · In contrast, the YR enzymes need to coordinate the cleavage, exchange and ligation of DNA strands between two active sites in the recombinase tetramer, while rendering the other two sites inactive. In the absence of such allosteric regulation, YR enzymes could generate double-strand breaks across the 6–8 bp overlap region.
WebRNA polymerase II (also called RNAP II and Pol II) is an enzyme found in eukaryotic cells. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA. In humans, RNAP II consists of seventeen protein molecules (gene products encoded by POLR2A-L, where the proteins synthesized from POLR2C, POLR2E, and … WebRecombination-activating gene. The recombination-activating genes (RAGs) encode parts of a protein complex that plays important roles in the rearrangement and recombination of the genes encoding immunoglobulin and T cell receptor molecules. There are two recombination-activating genes RAG1 and RAG2, whose cellular expression is …
