MALTOPORIN FROM SALMONELLA TYPHIMURIUM
Overview
The maltodextrin-specific (malto-)porin from Salmonella typhimurium has, been crystallized. Its three-dimensional structure was determined at 2.4 A, resolution (1 A = 0.1 nm). A comparison with the structure of the, homologous porin from Escherichia coli as well as with the sequences of, other related porins showed that there are regions of appreciable sequence, and structure variability, despite close overall similarity. The, maltoporin structure was analyzed with a bound nitrophenyl-maltotrioside, as well as without ligand. Maltotrioside binding had a negligible effect, on the polypeptide structure. It binds at the pore eyelet assuming a, conformation close to the natural amylose helix.
About this Structure
