These studies advance our knowledge of native Env via insights gained from cryo-53 ET of intact viral particles. 54 WebMar 2, 2024 · Using extensive all-atom molecular dynamics simulations of HIV-1 cores imaged from cryo-electron tomography (cryo-ET) in intact virions, which contain IP 6 and a ribonucleoprotein complex, we find markedly striated patterns of strain on capsid lattices. The presence of these cofactors also increases rigidity of the capsid.
Cryo-ET of HIV reveals Env positioning on Gag lattice and
WebCryo-electron tomography (cryo-ET) of intact cells, in combination with correlative approaches, is uniquely positioned to provide structural information across scales, from whole organisms to individual macromolecules. WebCryo electron tomography is a powerful imaging technique in structural biology that is ultimately suitable for investigation of macromolecular assemblies, organelles in vitro but also inside their native environment (Koning and Koster, 2009; Lucic et al., 2005). Biological structures like MTs can be visualized in their native environment in ... fs19 race car mods
