Cleavage of one specific disulfide bond in papain.
Conditions leading to cleavage of all of the disulfide bridges in ribonuclease and several other proteins (0.32 M Z-mercaptoethanol in 8 M urea) caused in papain only partial reduction of the disulfide bonds. Electrophoretic studies indicated that alkylation of the partially reduced derivative yielded a unique molecular species (3-RCM papain) in which one specific disulfide bond had been split,...
متن کاملSynthesis of Zinc Dimethyldithiocarbamate by Reductive Disulfide Bond Cleavage of Tetramethylthiuram Disulfide in Presence of Zn2+
The zinc(II) complex [Zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = N,N-dimethyldithiocarbamate; thiram = N,N-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. Surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with Zn2+ in methanolic media to give the [Z...

متن کاملOptimization of Nonenzymatic Microwave D-Cleavage and Disulfide Bond Cleavage
A nonenzymatic digestion technique allows proteins to be well suited for collision-induced dissociation tandem mass spectrometry. This method utilizes microwaves and Dithiothreitol (DTT) to selectively cleave at aspartic acid (D) and disulfide bonds. This microwave digestion technique is reproducible and produces peptides with a shortened sequence length. Insulin I is used in this study to opti...
