The X-ray structure of the periplasmic glucose/galactose receptor (binding protein) of Salmonella typhimurium (GBP-S) has been refined at 1.7 A resolution with an R-factor of 19.0%. The model contains all 309 residues of the amino acid sequence, 153 water molecules, a calcium ion and beta-D-galactose. The protein consists of two very similar structural domains, each of which is composed a core of parallel beta-sheet flanked on both sides by alpha-helices. Three short stretches of amino acid… CONTINUE READING
