conserved catalytic core domain of RNA-dependent RNA polymerase (RdRp) from the positive-sense single-stranded RNA [(+)ssRNA] viruses and closely related viruses; This family contains the catalytic core domain of RdRp of RNA viruses which belong to Group IV of the Baltimore classification system, and are a group of related viruses that have positive-sense (+), single-stranded (ss) genomes made of ribonucleic acid (RNA). RdRp (also known as RNA replicase) catalyzes the replication of RNA from an RNA template; specifically, it catalyzes the synthesis of the RNA strand complementary to a given RNA template. The Baltimore Classification is divided into 7 classes, 3 of which include RNA viruses: Group IV (+) RNA viruses, Group III double-stranded (ds) RNA viruses, and Group V negative-sense (-) RNA viruses. Baltimore groups of viruses differ with respect to the nature of their genome (i.e., the nucleic acid form that is packaged into virions) and correspond to distinct strategies of genome replication and expression. (+) viral RNA is similar to mRNA and thus can be immediately translated by the host cell. (+)ssRNA viruses can also produce (+) copies of the genome from (-) strands of an intermediate dsRNA genome. This acts as both a transcription and a replication process since the replicated RNA is also mRNA. RdRps belong to the expansive class of polymerases containing so-called palm catalytic domains along with the accessory fingers and thumb domains. All RdRps also have six conserved structural motifs (A-F), located in its majority in the palm subdomain (A-E motifs) and the F motif is located on the finger subdomain. All these motifs have been shown to be implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. In addition to Group IV viruses, this model also includes Picobirnaviruses (PBVs), members of the family Picobirnaviridae of dsRNA viruses (Baltimore classification Group III), which are bi-segmented dsRNA viruses. The phylogenetic tree of the RdRps of RNA viruses (realm Riboviria) showed that picobirnaviruses are embedded in the branch of diverse (+)RNA viruses; sometimes they are collectively referred to as the picornavirus supergroup. RdRps of members of the family Permutatetraviridae, a distinct group of RNA viruses that encompass a circular permutation within the RdRp palm domain, are not included in this model. The actual alignment was detected with superfamily member cd23204: Pssm-ID: 477363 [Multi-domain] Cd Length: 565 Bit Score: 180.83 E-value: 3.75e-56

1-77 | 3.75e-56 | ||
catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the genus Flavivirus, within the family Flaviviridae of positive-sense single-stranded RNA (+ssRNA) viruses; This group contains the catalytic core domain of the RdRp of RNA viruses belonging to the Flavivirus genus within the family Flaviviridae, order Amarillovirales. The genus Flavivirus consists of more than 50 species of arthropod-borne viruses, with distinct groups infecting mosquitoes or ticks. Mammals and birds are the usual primary hosts, in which infections range from asymptomatic to severe or fatal hemorrhagic fever or neurological disease. Important human pathogens include yellow fever virus, dengue virus, Japanese encephalitis virus, West Nile virus and tick-borne encephalitis virus. Other members cause economically important diseases in domestic or wild animals. Virions of Flavivirus have a single, small, basic capsid (C) protein and two envelope proteins. They contain a single, long ORF flanked by 5'- and 3'-terminal non-coding regions, which form specific secondary structures required for genome replication and translation. Translational initiation of genomic RNA is cap dependent in the case of members of the genus Flavivirus. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides.

Flavivirus RNA-directed RNA polymerase, fingers and palm domains; Flaviviruses produce a large polyprotein from the ssRNA genome, encoding structural proteins required for virus assembly and non-structural (NS1-5) proteins involved in replication of the viral genome. This polyprotein is cleaved by viral and cellular proteases to produce mature viral proteins. NS5 is the largest mature viral protein and contains a N-terminal methyltransferase (MTase) domain separated by a short linker from the C-terminal RNA-directed RNA polymerase domain (RdRp) that adopts a characteriztic right-handed fingers-palm-thumb fold and possesses a number of short regions and motifs homologous to other RNA-directed RNA polymerases. This entry covers the fingers and palm domains of RNA-directed RNA polymerase (RdRp) from Flavivirus NS5. NS5 binds to a the stem loop A (SLA) at the 5' extremity of Flavivirus genome and regulates translation of the viral genome. Pssm-ID: 460013 Cd Length: 451 Bit Score: 144.32 E-value: 4.30e-43

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Flaviviridae of positive-sense single-stranded RNA (+ssRNA) viruses; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Flaviviridae, order Amarillovirales. Flaviviridae, is a family of small, enveloped viruses with RNA genomes of 9-13 kb. Most infect mammals and birds. Many flaviviruses are host-specific and pathogenic, such as hepatitis C virus in the genus Hepacivirus. The majority of known members in the genus Flavivirus are arthropod borne, and many are important human and veterinary pathogens (e.g., yellow fever virus, dengue virus). Virions are typically spherical in shape with a lipid envelope. Virions have a single, small, basic capsid (C) protein and two (genera Flavivirus, Hepacivirus and Pegivirus) or three (genus Pestivirus) envelope proteins. They contain a single, long ORF flanked by 5'- and 3'-terminal non-coding regions, which form specific secondary structures required for genome replication and translation. Translational initiation of genomic RNA is cap dependent in the case of members of the genus Flavivirus.
