The N-Terminal Amino Acid Sequence of Two Avian Leukosis Group Specific Antigens*

AUTOR(ES)
RESUMO

Two group-specific antigenic proteins from an avian leukosis virus have been compared by amino acid analysis, tryptic peptide fingerprinting, and N-terminal sequence determination, and found to be dissimilar. There was microheterogeneity in the structure of the protein gs-b at residues 6; threonine and glutamic acid were found.
