Title: BtuB TonB-dependent transporters and BtuG surface lipoproteins form stable complexes for vitamin B uptake in gut Bacteroides.
Authors: Javier Abellon-Ruiz / Kalyanashis Jana / Augustinas Silale / Andrew M Frey / Arnaud Baslé / Matthias Trost / Ulrich Kleinekathöfer / Bert van den Berg /

Abstract: Vitamin B (cobalamin) is required for most human gut microbes, many of which are dependent on scavenging to obtain this vitamin. Since bacterial densities in the gut are extremely high, competition ...

Yorodumi

Thousand views of thousand structures

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
