title: Measles virus hemagglutinin. Removal of the initiator methionine in the mature protein, and evidence for further processing to produce a 'ragged' end.
abstract: Measles virus hemagglutinin has been isolated by immunoadsorption. The total composition of the protein and its N-terminal amino acid sequence give data matching the structure indirectly deduced from cDNA. However, direct analysis of the hemagglutinin also shows that the mature protein is proteolytically processed and has a partly heterogeneous N-terminus. The initiator Met is removed, and non-stoichiometrically also the second residue.
