Evidence: gel filtration, MsuC runs as a species of similar size to gamma globulin (150 kDa). The expected MW of the tetramer is ~180 kDa, therefore MsuC runs as a more compact structure by gel filtration.

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.
