Abstract
Tryptic peptide analyses were undertaken on the nucleocapsid (N) protein of snowshoe hare (SSH) and La Crosse (LAC) bunyaviruses. Similar analyses were performed on the N proteins of 2 recombinant viruses which were the large/medium/small RNA genome configurations: SSH/LAC/LAC and SSH/LAC/SSH. The S RNA of bunyaviruses apparently codes for the viral N protein.
