Structural insight into host plasma membrane association and assembly of HIV-1 matrix protein
BioXFEL Publications 4 Aug 2021 Contributor(s): Hasan Demirci
http://dx.doi.org/10.1038/s41598-021-95236-8 AbstractOligomerization of Pr55Gag is a critical step of the late stage of the HIV life cycle. It has been known that the binding of IP6, an abundant endogenous cyclitol molecule at the MA domain, has been linked to the oligomerization of Pr55Gag. However, the exact binding site of IP6 on MA remains…

http://dx.doi.org/10.1107/s2052252521008125 Here, we illustrate what happens inside the catalytic cleft of an enzyme when substrate or ligand binds on single-millisecond timescales. The initial phase of the enzymatic cycle is observed with near-atomic resolution using the most advanced X-ray source currently available: the European XFEL (EuXFEL).…

Cryo-EM model validation recommendations based on outcomes of the 2019 EMDataResource challenge
BioXFEL Publications 4 Feb 2021 Contributor(s): James Fraser
http://dx.doi.org/10.1038/s41592-020-01051-w AbstractThis paper describes outcomes of the 2019 Cryo-EM Model Challenge. The goals were to (1) assess the quality of models that can be produced from cryogenic electron microscopy (cryo-EM) maps using current modeling software, (2) evaluate reproducibility of modeling results from different software…

http://dx.doi.org/10.1107/s1600577521004045 X-ray-based techniques are a powerful tool in structural biology but the radiation-induced chemistry that results can be detrimental and may mask an accurate structural understanding. In the crystallographic case, cryocooling has been employed as a successful mitigation strategy but also has its…

http://dx.doi.org/10.1107/s2059798323007027 Over the past two decades, serial X-ray crystallography has enabled the structure determination of a wide range of proteins. With the advent of X-ray free-electron lasers (XFELs), ever-smaller crystals have yielded high-resolution diffraction and structure determination. A crucial need to continue…

http://dx.doi.org/10.1126/sciadv.abf8711 The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) macrodomain within the nonstructural protein 3 counteracts host-mediated antiviral adenosine diphosphate–ribosylation signaling. This enzyme is a promising antiviral target because catalytic mutations render viruses nonpathogenic. Here, we…

http://dx.doi.org/10.1093/icb/icab069 Abstract Many biological systems across scales of size and complexity exhibit a time-varying complex network structure that emerges and self-organizes as a result of interactions with the environment. Network interactions optimize some intrinsic cost functions that are unknown and involve for…
