-dihydroxyphenyl rings of procyanidin C1 have been present in the framework mimicking K2E2·Pi state. This interaction leads to the ion pathway (which is formed by residues such as one of several interacting arginines, R979) to become inaccessible in the extracellular side76. This binding mode may Therefore sterically impede ion exchange. https://wesleyd332ozj4.wikiinside.com/user
