Kinetic parameters have been measured for coupled nucleophilic and solvolytic reactions of 2,2,2-trifluoroethanesulfonyl (tresyl)-modified poly(ethylene glycol) based on a system of coupled differential equations implied by recently proposed elementary reaction mechanisms. Fitted kinetic parameters were found to be strong functions

Oligopeptides are efficiently hydrolyzed by Ce(IV) to the corresponding amino acids under mild conditions. The pseudo first-order rate constants for the hydrolysis of H-Gly-Phe-OH and H-Gly-Gly-OH at pH 7.0 and 50 degrees C are 3.5 x 10(-1) and 2.8 x

Natively unfolded phenylalanine-glycine (FG)-repeat domains are alleged to form the physical constituents of the selective barrier-gate in nuclear pore complexes during nucleocytoplasmic transport. Presently, the biophysical mechanism behind the selective gate remains speculative because of a lack of information regarding

The aim of this study was to improve the performance of affinity gels containing glycyl-D-phenylalanine (Gly-D-Phe) as a ligand to thermolysin. Gly-D-Phe was immobilized to the resin through spacers of varying chain lengths. The resulting affinity gels had spacer chain
