Comparison of the sequences and coding of La Crosse and snowshoe hare bunyavirus S RNA species. 1983

H Akashi, and D H Bishop

The sequence of the S RNA of La Crosse bunyavirus was deduced from analyses of DNA copies cloned in the Escherichia coli plasmid pBR322. The S RNA is 984 nucleotides in length, has a base ratio of 31.8% U, 27.0% A, 23.2% C, and 18.0% G, and codes for two distinct gene products that are read from overlapping reading frames in the viral complementary strand. The larger gene product (N, 26.5 x 10(3) daltons) contains 235 amino acids, and the smaller gene product (NSS, 10.4 x 10(3) daltons) has 92 amino acids. Comparisons with the published sequences of the related snowshoe hare bunyavirus S RNA and its gene products (Bishop et al., Nucleic Acids Res. 10:3703-3713, 1982) indicate that there are a total of 114 nucleotide differences (6 additions or deletions and 108 substitutions). Also, there are 22 amino acid differences between the N proteins and 12 amino acid differences between the NSS proteins of the two S RNAs.

UI	MeSH Term	Description	Entries
D002043	Bunyaviridae	A family of viruses, mainly arboviruses, consisting of a single strand of RNA. Virions are enveloped particles 90-120 nm diameter. The complete family contains over 300 members arranged in five genera: ORTHOBUNYAVIRUS; HANTAVIRUS; NAIROVIRUS; PHLEBOVIRUS; and TOSPOVIRUS.
D002141	Encephalitis Virus, California	A species in the ORTHOBUNYAVIRUS genus of the family BUNYAVIRIDAE. Serotypes are found in temperate and arctic regions and each is closely associated with a single species of vector mosquito. The vertebrate hosts are usually small mammals but several serotypes infect humans.

D003062	Codon	A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (CODON, TERMINATOR). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, TRANSFER) complementary to all codons. These codons are referred to as unassigned codons (CODONS, NONSENSE).
