Characterization of an Invisible HIV-1 Circulating Recombinant Form (CRF149_01B) in China.

In this study, by analyzing the available near full-length genome (NFLG) sequences of CRF55_01B, it was found that two of the NFLG sequences could not be clustered with other NFLG sequences. Recombination analysis and phylogenetic analysis suggested that these two NFLG sequences arose by recombination with subtype B based on CRF55_01B, rather than by recombination directly derived from CRF01_AE and subtype B. In addition, two other HIV-1 partial gene fragments found in the database shared the same characteristics as these two NFLG sequences in the key recombination region.

Viral RNA polymerase as a SUMOylation decoy inhibits RNA quality control to promote potyvirus infection.

Potyvirids are the largest group of plant RNA viruses. Pelota, a core component of RNA quality controls (RQC), promotes the degradation of potyvirids' genomic RNA by recognizing a specific GA motif. Here we demonstrate that the viral RNA-dependent RNA polymerase, NIb, acts as a SUMOylation decoy to effectively reduce Pelota SUMOylation by competing with SCE1 to inhibit Pelota-mediated RQC.

Water-Mediated Proton Hopping Mechanisms at the SnO(110)/HO Interface from Ab Initio Deep Potential Molecular Dynamics.

The interfacial proton transfer (PT) reaction on the metal oxide surface is an important step in many chemical processes including photoelectrocatalytic water splitting, dehydrogenation, and hydrogen storage. The investigation of the PT process, in terms of thermodynamics and kinetics, has received considerable attention, but the individual free energy barriers and solvent effects for different PT pathways on rutile oxide are still lacking. Here, by applying a combination of ab initio and deep potential molecular dynamics methods, we have studied interfacial PT mechanisms by selecting the rutile SnO(110)/HO interface as an example of an oxide with the characteristic of frequently interfacial PT processes.
