Abstract excerpt
The structure of the sucrose-specific porin (ScrY) from Salmonella typhimurium has been elucidated by X-ray crystallography to consist of 18 antiparallel beta-strands, associated as a trimer complex similar to ion-transport channels. However, the 71-amino-acid-residue N-terminal periplasmic domain was not determined from the crystal structure due to the absence of sufficient electron density. The N-terminal...
