We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Because life has more than 2D, Proteopedia helps to understand relationships between structure and function. Proteopedia is a free, collaborative 3D-encyclopedia of proteins & other molecules. ISSN 2310-6301

Avian Influenza Neuraminidase

Eric Martz
The first new influenza virus to emerge as an imminent pandemic threat in the 21st century is H1N1 swine flu. The drug oseltamivir (Tamiflu®) inhibits flu neuraminidase, a component necessary for virus spread, in susceptible flu strains. The development of oseltamivir was guided, in part, by crystallographically determined structures of flu neuraminidase, which is a homotetramer, shown with oseltamivir bound. Oseltamivir was designed to fit N2/N9 (neuraminidases from other strains of flu). Serendipitously, it also fits N1 by induced fit.

Geobacter pili: surprising function.

Y Gu, V Srikanth, AI Salazar-Morales, R Jain, JP O'Brien, SM Yi, RK Soni, FA Samatey, SE Yalcin, NS Malvankar. Nature 2021 doi: 10.1038/s41586-021-03857-w
Geobacter pili were long thought to be electrically conductive protein nanowires composed of PilA-N. Nanowires are crucial to the energy metabolism of bacteria flourishing in oxygen-deprived environments. To everyone's surprise, in 2019, the long-studied nanowires were found to be linear polymers of multi-heme cytochromes, not pili. The first cryo-EM structure of pili (2021) reveals a filament made of dimers of PilA-N and PilA-C, shown. Electrical conductivity of pili is much lower than that of cytochrome nanowires. Evidence suggests that PilA-NC filaments are periplasmic pseudopili crucial for exporting cytochrome nanowires onto the cell surface, rather than the pili serving as nanowires themselves.

Touch-Sensitive Channel

Touching stretches cell membranes, opening mechanosensitive ion channels, leading to sensation by the nervous system. Pictured is the transmembrane region of a similar channel in bacteria. When closed, the narrow opening is lined by hydrophobic amino acid sidechains, making it non-conductive to ions.
