Solvent affinity
WebPolar aprotic solvents form strongly hydrogen bonded complexes with the free carboxyl groups and thus lead to equilibrium constants in excess of 105l/mol at ambient conditions6. However, if the polymerization reaction is carried out in ether or hydrocarbon solvents, considerable differences in equilibrium constant are observed WebAuthor(s): Kobori, Evan Advisor(s): Taylor, Susan Abstract: Since the crystal structure of PKA was solved over thirty years ago, the overall kinase core has been well characterized; various structures have elucidated the overall catalytic cycle and internal interactions required for an active kinase. However, the function and regulation of full-length (FL) …
