The genome of the lipid-containing bacteriophage phi 6 contains three segments of double-stranded RNA. We have determined the nucleotide sequence of cDNA derived from the middle-size RNA segment. The coding sequences of three proteins on this segment were identified on the basis of size and the correlation of predicted N-terminal amino acid sequences with those found through the analysis of isolated proteins. In contrast to our results with the small phi 6 dsRNA segment, the open reading frames are not tightly clustered. The homologous terminal noncoding regions between the middle and small dsRNA segments are found to be more extensive than RNA sequencing had previously indicated.

UI MeSH Term Description Entries
D011549 Pseudomonas A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants. Chryseomonas,Pseudomona,Flavimonas
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). Codon, Sense,Sense Codon,Codons,Codons, Sense,Sense Codons
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D012317 RNA Phages Bacteriophages whose genetic material is RNA, which is single-stranded in all except the Pseudomonas phage phi 6 (BACTERIOPHAGE PHI 6). All RNA phages infect their host bacteria via the host's surface pili. Some frequently encountered RNA phages are: BF23, F2, R17, fr, PhiCb5, PhiCb12r, PhiCb8r, PhiCb23r, 7s, PP7, Q beta phage, MS2 phage, and BACTERIOPHAGE PHI 6.

D012330 RNA, Double-Stranded RNA consisting of two strands as opposed to the more prevalent single-stranded RNA. Most of the double-stranded segments are formed from transcription of DNA by intramolecular base-pairing of inverted complementary sequences separated by a single-stranded loop. Some double-stranded segments of RNA are normal in all organisms. Double-Stranded RNA,Double Stranded RNA,RNA, Double Stranded
