Structure of outer membrane protein G in lipid bilayers

open access: yesNature Communications, 2017
Porins, like OmpG, are embedded in the outer membrane of bacteria and facilitate uptake and secretion of nutrients and ions. Here the authors present a protocol for solid state NMR structure determination of proteins larger than 25 kDa and use it to ...
