Abstract
The sequence of the CNBr fragments of 1 of the major outer membrane proteins of E. coli B/r was established with the aim of elucidating the primary structure of this protein. Separation of all fragments on 1 molecular sieve column was achieved upon citraconylation of these fragments. Overlapping peptides were obtained by digestion of the protein, or a CNBr fragment arising from incomplete cleavage, with trypsin or Staphylococcus aureus protease.
