Many studies of the eukaryotic transcription mechanism and its regulation rely on in vitro assays. Conventional RNA polymerase II transcription assays are based on radioactive labelling of the newly synthesized RNA. Due to the inefficient in vitro transcription, the detection of the RNA involving purification and gel electrophoresis is laborious and not(More)
The allosteric enzyme aspartate transcarbamylase (ATCase) from E. coli shows homotropic cooperative interactions between its six catalytic sites for the binding of the substrate aspartate. This cooperativity is explained by the transition of the enzyme from a conformation which has a low affinity for aspartate (T state) to a conformation with high affinity(More)
