The SARS-CoV-2 betacoronavirus uses its highly glycosylated trimeric Spike protein to bind to the cell surface receptor angiotensin converting enzyme 2 (ACE2) glycoprotein and facilitate host cell entry. We utilized glycomics-informed glycoproteomics to characterize site-specific microheterogeneity of glycosylation for a recombinant trimer Spike mimetic immunogen and for a soluble version of human ACE2. We combined this information with bioinformatics analyses of natural variants and with existi ...[more]

Structural dynamics in the evolution of SARS-CoV-2 spike glycoprotein: HDX-MS analysis of the spike of alpha, beta, delta and omicron variants - in apo state and in complex with the ACE2 receptor

Project description:The spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mediates binding to the ACE2 receptor and subsequent membrane fusion. It exists in a range of conformations, including a closed state unable to bind the ACE2 receptor, and an open state that does so but displays more exposed antigenic surface. Spikes of variants of concern (VOCs) acquired amino acid changes linked to different opening probabilities, increased SARS-CoV-2 virulence and immune evasion. Here, using hydrogen-deuterium exchange mass spectrometry (HDX-MS), we analyzed the spike of the original Wuhan isolate, G614 mutant, spike of alpha, beta, delta and omicron VOCs and the isolated ancestral receptor binding domain (RBD) - in apo state and in complex with the ACE2 receptor. We identified changes in spike dynamics that we associated with the transition from closed to open conformation, to ACE2 binding, and to specific mutations in VOCs. We show that the RBD-associated subdomain plays a role in spike opening, whereas the NTD acts as a hotspot of conformational divergence of VOC spikes driving immune evasion. Alpha, beta and delta spikes assume predominantly open conformations and a strong ACE2 binding increases the dynamics of their core helices, priming spikes for fusion. Conversely, substitutions in omicron spike lead to predominantly binding-incompetent closed conformations, presumably enabling it to escape antibodies. At the same time, its core helices show characteristics of being pre-primed for fusion even in the absence of ACE2. These data inform on SARS-CoV-2 evolution and omicron variant emergence.

LC-MSMS of HEK 293T cells transfected with Flag-EV or Flag-ACE2

Project description:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of coronavirus disease 2019 (COVID-19). Alongside investigation into the virology of SARS-CoV-2, understanding the host–virus dependencies are vital for the identification and rational design of effective antiviral therapy. Here, we report the dominant SARS-CoV-2 entry receptor, ACE2, conjugates with small ubiquitin-like modifier 3 (SUMO3) and pharmacological intervention of ACE2 SUMOylation blocks SARS-CoV-2 infection as well as viral infection-triggered immune responses. E3 SUMO ligase PIAS4 prompts the SUMOylation and stabilization of ACE2, whereas deSUMOylation enzyme SENP3 reverses this process. Conjugation of SUMO3 with ACE2 at lysine (K) 187 hampers the K48-linked ubiquitination of ACE2, thus suppressing its subsequent cargo receptor TOLLIP-dependent autophagic degradation. TOLLIP depletion leads to the accumulation of ACE2 and the elevated SARS-CoV-2 infection. Collectively, our findings suggest selective autophagic degradation of ACE2 orchestrated by SUMOylation and ubiquitination can be targeted to future antiviral therapy of SARS-CoV-2.

Regulation by the homologous Ace2 and Swi5 factors of Saccharomyces cerevisiae

Project description:The homologous Ace2 and Swi5 transcription factors of Saccharomyces cerevisiae have identical DNA-binding domains, and both are cell cycle regulated. There are common target genes, as well as genes activated only by Ace2 and other genes activated only by Swi5. Keywords: genetic modification RNA was isolated from four strains: wild type, ace2 gene deletion, swi5 gene deletion, and the ace2 swi5 double gene deletion. RNAs from the three mutant strains were compared to wild type RNA in a microarray hybridization experiment.

MDM2 influences ACE2 stability and SARS-Cov2 uptake

Project description:The Angiotensin-converting enzyme 2 (ACE2) receptor is the central entry point for SARS-Cov2. Several SAR-Cov2 substrains have developed mutations in their spike protein to maximize their use of ACE2, e.g. to strengthen ACE2 binding for increased uptake or adapt to specific amino acid properties of ACE2 to cross the species barrier. But little is known about the effect of host regulators on ACE2 and subsequently their impact on SARS-Cov2 infection. Here we identify the E3 ligase MDM2 as a ACE2 modulator. The knockout of MDM2 induced a strong pro-viral effect specific for SARS-Cov2 and we could see the increase of ACE2 levels. This effect is likely dependent on the ubiquitination site Lysine 788, which MDM2 uses to induce proteasomal degradation of ACE2. Substituting this amino acid led to increased ACE2 levels and increased SARS-CoV2 infection facilitated by enhanced SARS-Cov2 uptake.
