title: Structure of tomato bushy stunt virus. V. Coat protein sequence determination and its structural implications.
abstract: We report the chemically determined sequence of most of the polypeptide chain of the coat protein of tomato bushy stunt virus. Peptide locations have been determined by comparison with the high-resolution electron density map from X-ray crystallographic analysis as well as by conventional chemical overlaps. Three small gaps remain in the 387-residue sequence. Positively charged side-chains are concentrated in the N-terminal part of the polypeptide (the R domain) as well as on inward-facing surfaces of the S domain. There is homology of S-domain sequences with structurally corresponding residues in southern bean mosaic virus.
