The structure of the turnip crinkle virus (TCV) coat protein and coat protein gene has been examined by cDNA cloning, nucleotide sequencing and high-resolution mRNA mapping. We have cloned a 1450-nucleotide cDNA fragment, representing the 3' end of the TCV genome, using genomic RNA polyadenylated in vitro as the reverse transcriptional template. Nucleic acid sequence analysis reveals the presence of a 1053 nucleotide open reading frame capable of encoding a protein of 38,131 Mr, identified as the coat protein subunit. The 1446 base subgenomic mRNA for the coat protein, mapped using high-resolution primer extension techniques, contains a 137 nucleotide leader sequence upstream from the initiation codon. We have characterized a second subgenomic RNA of approximately 1700 bases, roughly 250 nucleotides longer than the 1446 base species in the 5' direction. No TCV-related RNAs are polyadenylated in vivo. The derived amino acid sequence of the TCV coat protein has been built into the 3.2 A resolution electron density map of TCV reported in paper I of this series. We describe here some of the important features of the structure. Alignment of the three-dimensional structures of tomato bushy stunt virus and southern bean mosaic virus shows significant sequence relationships in the arms and S domains, although the conserved residues do not appear to have any special role in stabilizing the beta-barrel fold or in mediating subunit interactions. The sequences of TCV and carnation mottle virus can be aligned. Comparisons among the four are discussed in terms of the organization of the S domain.
