Mutations in Coronavirus Spike Protein by Eric Martz Black spots are mutations of concern in SARS-CoV-2 spike protein reported by UK scientists in December, 2020. RNA viruses mutate quickly so mutations are expected. These mutations may speed up contagion, but are unlikely to cause more severe COVID-19 and unlikely to reduce vaccine effectiveness.

F Wang, Y Gu, JP O'Brien, SM Yi, SE Yalcin, V Srikanth, C Shen, D Vu, NL Ing, AI Hochbaum, EH Egelman, NS Malvankar. Cell 2019 doi: 10.1016/j.cell.2019.03.029 Bacteria living in anaerobic environments (no oxygen) need alternative electron acceptors in order to get energy from their food. An acceptor abundant in the earth's crust is red iron oxide ("rust"), which gets reduced to black iron oxide (magnetite). Many bacteria, such as Geobacter, get their metabolic energy by transferring electrons to acceptors that are multiple cell diameters distant, using protein nanowires. These were long thought to be pili. But when the structure of the nanowires was solved in 2019, to everyone's surprise, they turned out to be unprecedented linear polymers of multi-heme cytochromes. The hemes form an electrically conductive chain in the cores of these nanowires. >>> Visit I3DC Interactive Visualizations >>>	Teaching strategies using Proteopedia Examples of pages for teaching How to add content to Proteopedia You Are What You Eat! Above is an integral membrane protein that takes up, into your intestinal cells, orally consumed peptide nutrients and drugs. Its lumen-face (top) opens and binds peptide or drug (small solid object in the center), then closes, while its cytoplasmic face (bottom) opens to release its cargo into the intestinal cell, which passes it on to the blood circulation. >>> See more animations and explanation >>>
