Mutational analysis of the conserved cysteine-rich region of the human immunodeficiency virus type 1 Tat protein.

Extracts prepared from either mouse cells or monkey cells were examined for the ability to support in vitro bovine papillomavirus type 1 (BPV1) DNA replication, and they were used

The complete sequence of the BDV genome presented here has revealed a modular genomic organization similar to that displayed by other members of the Mononegavirales order, with

Rescue of the chimeric virus FLUBCYT, in which the WSN NA cytoplasmic tail is replaced by the influenza B virus NA tail, indicates that the cytoplasmic tails of influenza viruses A

Ribozymes have been shown to exert a limited effect on one animal virus, the human retrovirus human immunodefi- ciency virus type 1 (HIV-1), in cell culture; an anti-HIV-1

D371 substitution in GP12.D371 (Fig. 6A), the yield of active RT was reduced even further than with GP15.D37I (down to J.. Summary of phenotypes observed in coexpression

Homologous DNA recombination within cells infected with vaccinia virus was used for the deletion or replacement of promoter sequences of the viral growth factor gene by a

A single extra G is also found by cloning the 5' ends of S antigenomes, and studies with capping enzyme detect (p)ppG at the 5' ends of genome and antigenome chains.. A model

unedited mRNA was shown to encode the mumps virus cysteine-rich protein V, and mRNA transcripts containing two and four inserted G residues were translated to yield the mumps virus
