ps-ssRNAv_Nodaviridae_RdRp cd23173
catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Nodaviridae of ...
497-734 1.58e-124

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Nodaviridae of positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Nodaviridae, order Nodamuvirales. The family name Nodaviridae, derives from the Japanese village of Nodamura where Nodamura virus was first isolated from Culex tritaeniorhynchus mosquitoes. Virions are non-enveloped and spherical in shape with icosahedral symmetry and diameters ranging from 25 to 33 nm. The members of the two genera in this family infect insects (Alphanodavirus) or fish (Betanodavirus). Alphanodavirus infection results in the stunting, paralysis and death of the insect host. The infection of fish by betanodaviruses such as striped jack nervous necrosis virus or red-spotted grouper nervous necrosis virus causes neural necrosis, encephalopathy or retinopathy and is associated with behavioral abnormalities and high mortality, posing significant problems for marine aquaculture. The genome consists of two molecules of (+)ssRNA: RNA1 and RNA2. 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.

510-714 2.29e-18

catalytic core domain of RNA-dependent RNA polymerase (RdRp) chronic bee paralysis virus (CBPV) and related positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the catalytic core domain of RdRp of the chronic bee paralysis virus (CBPV) and related (+)ssRNA viruses. The CBPV is the causative agent of severe, usually fatal, paralysis in adult honey bees. CBPV has not been assigned to any group or class of viruses because it has a unique genome organization and virion morphology. However, analyses of the nucleic acid sequence showed similarities between the RdRp of CBPV and the RdRps of Tombusviruses, Nodaviruses, Lake Sinai virus 1 and 2 as well as the Anopheline associated C virus (AACV). CBPV was one of the first viruses in honey bees to be described and isolated as it causes characteristic signs of disease in adult honey bees. 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.

571-747 2.09e-09

RNA_dep_RNAP: RNA-dependent RNA polymerase (RdRp) is an essential protein encoded in the genomes of all RNA containing viruses with no DNA stage. RdRp catalyzes synthesis of the RNA strand complementary to a given RNA template. RdRps of many viruses are products of processing of polyproteins. Some RdRps consist of one polypeptide chain, and others are complexes of several subunits. The domain organization and the 3D structure of the catalytic center of a wide range of RdRps, including those with a low overall sequence homology, are conserved. The catalytic center is formed by several motifs containing a number of conserved amino acid residues. This subfamily represents the RNA-dependent RNA polymerases from all positive-strand RNA eukaryotic viruses with no DNA stage.

574-688 4.38e-06

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the order Picornavirales of positive-sense single-stranded RNA [(+)ssRNA] viruses; This family contains the catalytic core domain of RdRp of Picornavirales, an order of (+)ssRNA viruses. The order Picornavirales comprises viruses that historically are referred to as picorna-like viruses and which are classified into eight virus families: Caliciviridae, Dicistroviridae, Iflaviridae, Marnaviridae, Picornaviridae, Polycipiviridae, Secoviridae, and Solinviviridae. All known genomes of Picornavirales members encode proteins with helicase, 3C-like protease, and RdRp domains, as well as capsid proteins with related structures, although the genome organizations can differ among viruses. The picornavirus genome is replicated via a negative-sense (-) RNA intermediate by the viral RdRp, named 3Dpol, which uses VPg (the product of 3B) as a primer to initiate the replication process. 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.

581-694 5.96e-06

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.

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the order Nidovirales of positive-sense single-stranded RNA [(+)ssRNA] viruses; This family contains the catalytic core domain of RdRP of Nidovirales, an order of enveloped, (+)ssRNA viruses which infect vertebrates and invertebrates. Host organisms include mammals, birds, reptiles, amphibians, fish, arthropods, mollusks, and helminths. The order Nidovirales currently comprises 88 formally recognized virus species of (+)ssRNA viruses which are classified into nine virus families: Abyssoviridae, Arteriviridae, Coronaviridae, Euroniviridae, Medioniviridae, Mesoniviridae, Mononiviridae, Roniviridae, and Tobaniviridae. Based on the genome size, the members of the order Nidovirales can be divided into two groups, large and small nidoviruses. The genomes of the large nidoviruses are well over 25 kb in length with size differences in the 5 kb range. Planarian secretory cell nidovirus (PSCNV), only member of the Mononiviridae family, has the largest known non-segmented RNA genome of 41.1 kb; its host is the planarian flatworm. 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.
