Structural polypeptides of Sendai virus: analysis by tryptic peptide mapping.

Tryptic peptide patterns identified Sendai virus polypeptides polypeptides HN, HN, P,F0, NP, and M as unique gene products, and confirmed the precursor-product relationship of polypeptides F0 and F. By the same criterion, the major nucleocapsid polypeptides, P and NP, in virions were derived from the same genes as their counterparts in nucleocapsids obtained from infected cells.
