title: Major proteins of the Escherichia coli outer cell envelope membrane. Sequence of the cyanogen bromide fragments of protein I from Escherichia coli B/r.
abstract: The sequence of the cyanogen bromide fragments of one of the major outer membrane proteins of E. coli B/r has been established with the aim of elucidating the primary structure of this protein. Separation of all fragments on one molecular sieve column was achieved upon citraconylation of these fragments. Overlapping peptides were obtained by digestion of the protein, or a cyanogen bromide fragment arising from incomplete cleavage, with trypsin or Staphylococcus aureus protease.
