Fig. 5. Comparison of peptide sequences at structural protein cleavage sites. (A) Schematic representation of structural protein cleavage patterns for BQCV (SA), PSIV, RhPV and DCV. Boxed labels CP1 to CP4 refer to the mature capsid proteins of BQCV (SA). Dark horizontal lines represent capsid proteins in each case. Numbers 1 to 3 in reverse type indicate cleavage sites in the BQCV capsid protein; dotted lines indicate equivalents in the other proteins. Numbers above each line represent the number of amino acids between each cleavage site. (B) Alignment of peptide sequences at cleavage site (2). (C) Alignment of peptide sequences at cleavage sites (1) and (3). In each case, the number in parentheses corresponds to the cleavage site. The position of each cleavage site relative to the corresponding capsid polyprotein sequence is shown at the beginning of each sequence. The scissile bond of the cleavage site is represented by a forward slash.
