Abstract

Particles of {delta}ProCANC, a fusion of capsid (Canada) and nucleocapsid (NC) protein of Mason-Pfizer monkey virus (M-PMV), which lacks the amino terminal proline, were reassembled in vitro and visualized by atomic force microscopy (AFM). The particles, of 83-84 nm diameter, exhibited ordered domains based on trigonal arrays of prominent rings with center to center distances of 8.7 nm. Imperfect closure of the lattice on the spherical surface was affected by formation of discontinuities. The lattice is consistent only with plane group p3 where one molecule is shared between contiguous rings. There are no pentameric clusters nor evidence that the particles are icosahedral. Tubular structures were also reassembled, in vitro, from two HIV fusion proteins, {delta}ProCANC and CANC. The tubes were uniform in diameter, 40 nm, but varied in length to a maximum of 600 nm. They exhibited left handed helical symmetry based on a p6 hexagonal net. The organization of HIV fusion proteins in the tubes is significantly different than for the protein units in the particles of M-PMV {delta}ProCANC.

Conformational changes of the N-terminal part of Mason-Pfizer monkey virus p12 protein during multimerization

Journal Article Knejzlik, Zdenek ; Ulbrich, Pavel ; Strohalm, Martin ; ... - Virology

The Mason-Pfizer monkey virus is a prototype Betaretrovirus with the defining characteristic that it assembles spherical immature particles from Gag-related polyprotein precursors within the cytoplasm of the infected cell. It was shown previously that the N-terminal part of the Gag p12 domain (wt-Np12) is required for efficient assembly. However, the precise role for p12 in mediating Gag-Gag interaction is still poorly understood. In this study we employed detailed circular dichroism spectroscopy, electron microscopy and ultracentrifugation analyses of recombinant wt-Np12 prepared by in vitro transcription and translation. The wt-Np12 domain fragment forms fibrillar structures in a concentration-dependent manner. Assembly into fibersmore »« less

A single amino acid substitution within the transmembrane domain of the human immunodeficiency virus type 1 Vpu protein renders simian-human immunodeficiency virus (SHIV{sub KU-1bMC33}) susceptible to rimantadine

Journal Article Hout, David R. ; Gomez, Lisa M. ; Pacyniak, Erik ; ... - Virology

Previous studies from our laboratory have shown that the transmembrane domain (TM) of the Vpu protein of human immunodeficiency virus type 1 (HIV-1) contributes to the pathogenesis of SHIV{sub KU-1bMC33} in macaques and that the TM domain of Vpu could be replaced with the M2 protein viroporin from influenza A virus. Recently, we showed that the replacement of the TM domain of Vpu with that of the M2 protein of influenza A virus resulted in a virus (SHIV{sub M2}) that was sensitive to rimantadine [Hout, D.R., Gomez, M.L., Pacyniak, E., Gomez, L.M., Inbody, S.H., Mulcahy, E.R., Culley, N., Pinson, D.M.,more »« less

Characterization of Mason--Pfizer monkey virus-induced cell fusion. [uv radiation]

Journal Article Chatterjee, S. ; Hunter, E. - Virology; (United States)

The characteristics and requirements of multinucleate cell (syncytium) induction by Mason--Pfizer monkey virus (M-PMV) on human and non-human primate cells have been investigated. Multinucleate cell induction by this D-type retrovirus shows single-hit kinetics on human foreskin and rhesus monkey fetal lung cells. The peak of syncytium-forming activity in an isopycnic sucrose gradient coincides with the peak of M-PMV virions as assessed by electron microscopy and analysis of viral polypeptides. Unlike the paramyxoviruses, M-PMV does not induce early cell fusion when added in high concentrations to the target cells. Furthermore, multinucleate cell formation is maximal 48 hr postinfection and the sizemore »« less

Antigenic analysis of the major structural protein of the Mason-Pfizer monkey virus. [/sup 125/I tracer technique]

Journal Article Schochetman, G. ; Boehm-Truitt, M. ; Schlom, J. - J. Immunol.; (United States)

The major internal protein, p27 (m.w. 27,000 daltons) of the Mason-Pfizer monkey virus (MPMV) was purified by gel filtration and ion-exchange chromatography and then used to develop a radioimmunoassay (RIA). This RIA was specific for MPMV because no immunologic cross-reactivity was observed between p27 of MPMV and 13 different RNA tumor viruses of mammalian and avian origin. However, the p27 of MPMV grown in three different primate cells exhibited identical antigenic cross-reactivity. In addition, significant levels of p27 were found only in MPMV-infected cells. These results indicate that synthesis of p27 is induced after virus infection and that p27 representsmore » a viral-coded protein.« less
Crystallization and preliminary X-ray studies of dUTPase from Mason–Pfizer monkey retrovirus

Journal Article Barabás, Orsolya ; Németh, Veronika ; Vértessy, Beáta G., E-mail: vertessy@enzim.hu - Acta Crystallographica. Section F

Deoxyuridine 5′-triphosphate nucleotidohydrolase from Mason–Pfizer monkey retrovirus (M-PMV dUTPase) is a betaretroviral member of the dUTPase enzyme family. The nucleocapsid-free dUTPase (48426 Da) was co-crystallized with a dUTP substrate analogue using the hanging-drop vapour-diffusion method. Deoxyuridine 5′-triphosphate nucleotidohydrolase from Mason–Pfizer monkey retrovirus (M-PMV dUTPase) is a betaretroviral member of the dUTPase enzyme family. In the mature M-PMV virion, this enzyme is present as the C-terminal domain of the fusion protein nucleocapsid-dUTPase. The homotrimeric organization characteristic of dUTPases is retained in this bifunctional fusion protein. The fusion protein supposedly plays a role in adequate localization of dUTPase activity in the vicinitymore »« less
