Transcription of hepatitis delta virus RNA by RNA polymerase II.
Previous studies have indicated that the replication of the RNA genome of hepatitis delta virus (HDV) involves redirection of RNA polymerase II (Pol II), a host enzyme that normally uses DNA as a template. However, there has been some controversy about whether in one part of this HDV RNA transcription, a polymerase other than Pol II is involved. The present study applied a recently described ce...
متن کاملDistinction and relationship between elongation rate and processivity of RNA polymerase II in vivo.
A number of proteins and drugs have been implicated in the process of transcriptional elongation by RNA polymerase (Pol) II, but the factors that govern the elongation rate (nucleotide additions per min) and processivity (nucleotide additions per initiation event) in vivo are poorly understood. Here, we show that a mutation in the Rpb2 subunit of Pol II reduces both the elongation rate and proc...
متن کاملThe nucleoside triphosphatase and helicase activities of vaccinia virus NPH-II are essential for virus replication.
Vaccinia virus NPH-II is the prototypal RNA helicase of the DExH box protein family, which is defined by six shared sequence motifs. The contributions of conserved amino acids in motifs I (TGVGKTSQ), Ia (PRI), II (DExHE), and III (TAT) to enzyme activity were assessed by alanine scanning. NPH-II-Ala proteins were expressed in baculovirus-infected Sf9 cells, purified, and characterized with resp...
