Analysis of 100 kDa polypeptides from coated vesicles of bovine brain: two-dimensional tryptic and chymotryptic maps
Authors:N V Ketis
Abstract:Two-dimensional peptide map analysis was used to determine the structural homology among the '100 kDa'-group of polypeptides. There are at least six distinct polypeptides whose apparent molecular weights are 116, 113, 111, 108, 105 and 100 kDa. The molar ratio of the '100 kDa'-group of polypeptides to three clathrin monomers (equivalent to one triskelion) is 1.2:1. There are three families of polypeptides in the '100 kDa'-group as determined by two-dimensional peptide map analysis. They are 116 and 113 kDa polypeptides, 111, 108, and 105 kDa polypeptides and 100 kDa polypeptide. However, all six polypeptides apparently show a series of homologous peptides. It is suggested that the 100-116 kDa polypeptides may bind to triskelions at the area of homology that is found in the 100-116 kDa polypeptides.
