Rhizobium meliloti (strain 1021) (Ensifer meliloti) (Sinorhizobium meliloti)

Length

228 amino acids

AlphaFoldDB

AF-Q92NM3-F1-model_v4.pdb

Function

Channel that permits osmotically driven movement of water in both directions. It is involved in the osmoregulation and in the maintenance of cell turgor during volume expansion in rapidly growing cells. It mediates rapid entry or exit of water in response to abrupt changes in osmolarity.
