The major soluble eye lens protein, αA-crystallin, has a very long half-life. Thus, many post-translational modifications, including stereoinversion, have been found in its constituent amino acids. We determine the rates of β-linkage isomerization, which is the main reaction through the

A one-pot, two-step method to prepare 3-halohydrofurans efficiently by TfOH-catalyzed hydroxylation/halocyclization of cyclopropyl methanols with H(2)O and N-halosuccinimide (NXS, X=1, Br, Cl) or Selectfluor is described. The reactions proceed rapidly under mild and operationally straightforward conditions with a catalyst loading

The rapid racemization of aspartic acid (Asp) residues in peptides and proteins is due mainly to the succinimide intermediate. However, there should be another mechanism for Asp racemization without intermediacy of the succinimide. The direct H-atom abstraction from the C(alpha)-atom

A thermally stressed Fab molecule showed a significant increase of basic variants in imaged capillary isoelectric focusing (iCIEF) analysis. Mass analyses of the reduced protein found an increase in -18Da species from both light chain and heavy chain. A tryptic

Protein chemical degradations occur naturally into living cells as soon as proteins have been synthesized. Among these modifications, deamidation of asparagine or glutamine residues has been extensively studied, whereas the intermediate state, a succinimide derivative, was poorly investigated because of
