Webb20 dec. 2024 · The viral RNA-dependent RNA polymerase (RdRp) is a key enzyme responsible for transcription and replication of viral genomes. Three-dimensional complete protein structures are available for RdRps from different RNA viruses and feature a similar “right handed” structure containing six conserved motifs [ 1 – 3 ].

Webb12 apr. 2024 · For assembly of RNP complexes, this usually involves induced fit of the RNA rather than the protein, or else a mutual induced fit of both protein and RNA (9, 11, 71, 72). Induced fit can be considered a special case of conformational selection but the two are often viewed as competing models ( 73 , 74 ).
WebbThe initial Gag-gRNA interaction that forms the vRNP complex has been thought to occur in the cytoplasm or at the plasma membrane where budding ensues [4,5,6,7,8]. However, this traditional assembly model was challenged by the discovery that the RSV Gag protein transiently localizes to the nucleus, a requirement for efficient gRNA packaging [9,10].
Webb28 jan. 2013 · The spliceosome is one of the largest complexes in the cell, and it is composed of ~200 snRNPs and five snRNAs [ 26 ]. Accumulating data suggest that mRNA splicing plays an important role in controlling circadian clock. However, whether splicing is under the control of a circadian clock is lacking substantial evidence. bosch process equationWebbGeldanamycin blocks assembly of active telomerase in vivo.
