Molecular cloning of cDNA from foot-and-mouth disease virus C1-Santa Pau (C-S8). Sequence of protein-VP1-coding segment.

cDNA segments copied from the RNA of foot-and-mouth disease virus (FMDV) C1-Santa Pau (isolate C-S8) have been cloned in plasmid pBR322. A 998-bp DNA fragment, that includes the region coding for capsid protein VP1, the carboxy terminus of VP3, and the amino terminus of precursor protein p52 has been sequenced. Comparison of the nucleotide sequence with those from FMDV O1K, A(10)61, A12 and C3 Indaial (Kurz et al., Nucl. Acids Res. 9 (1981) 1919-1931; Kleid et al., Science 214 (1981) 1125-1129; Boothroyd et al., Gene 17 (1982) 153-161; Makoff et al., Nucl. Acids Res. 10 (1982) 8285-8295) indicates extensive variability between the corresponding gene segments, including short insertions and deletions. Base transversions are more frequent than transitions within the VP1 coding segment, but not in the sequence coding for the amino-terminal end of p52. The nucleotide sequence divergence is reflected in variability in both the primary and the predicted higher-order structures of the encoded VP1s.
