TL;DR: It can be concluded that hydrophobic interaction is important for binding and that the combining size of the lectin is at least as large as a disaccharide, and of the compounds studied is most complementary to a mucintype disaccharacteride on a human erythrocyte membrane.

TL;DR: In this article, the effective atomic numbers and electron densities of the amino acids glycine, alanine, serine, valine, threonine, leucine and raffinose were calculated by using the measured total attenuation cross-sections.
Abstract: The effective atomic numbers and electron densities of the amino acids glycine, alanine, serine, valine, threonine, leucine, isoleucine, aspartic acid, lysine, glutamic acid, histidine, phenylalanine, arginine, tyrosine, tryptophane and the sugars arabinose, ribose, glucose, galactose, mannose, fructose, rhamnose, maltose, melibiose, melezitose and raffinose at the energies 30.8, 35.0, 81.0, 145, 276.4, 302.9, 356, 383.9, 661.6, 1173 and 1332.5 keV were calculated by using the measured total attenuation cross-sections. The interpolations of total attenuation cross-sections for photons of energy E in elements of atomic number Z was performed using the logarithmic regression analysis of the XCOM data in the photon energy region 30–1500 keV. The best-fit coefficients obtained by a piece wise interpolation method were used to find the effective atomic number and electron density of the compounds. These values are found to be in good agreement with the theoretical values calculated based on XCOM data.

TL;DR: The structural basis for the specificity of the channel is investigated by X-ray structure analysis of maltoporin in complex with the disaccharides sucrose, trehalose, and melibiose, which sheds light on the basis for sugar discrimination, and explains the different permeation rates observed for the saccharides.

TL;DR: Y. intermedia is positive in reactions for melibiose, raffinose, α-methyl-d-glucoside, rhamnose, and usually Simmons' citrate, and it is metabolically more active at 22–28°C than at 35–37°C.
Abstract: Yersinia intermedia sp. nov. is defined biochemically and genetically.Y. intermedia strains belong to a single DNA relatedness group that is separable fromY. enterocolitica, Y. frederiksenii, Y. kristensenii, andY. pseudotuberculosis. Y. intermedia is positive in reactions for melibiose, raffinose, α-methyl-d-glucoside, rhamnose, and usually Simmons' citrate. It is metabolically more active at 22–28°C than at 35–37°C. These positive reactions serve to distinguishY. intermedia fromY. enterocolitica andY. kristensenii. Positive melibiose, raffinose, and α-methyl-d-glucoside reactions differentiateY. intermedia from the other new rhamnose-positive species,Y. frederiksenii. Y. intermedia is separated fromY. pseudotuberculosis by its positive reactions for sucrose, indole, cellobiose,i-inositol,d-sorbitol, α-methyl-d-glucoside, and ornithine decarboxylase.Yersinia biotype X2, an additional rhamnose-positive, sucrose-negative group, as yet not identified to a species, and X1, a sucrose- and ornithine decarboxylase-negativeYersinia biotype, do not belong toY. intermedia. Strain 3953 (=CIP 80-28=ATCC 29909=Bottone 48=Chester 48) is proposed as the type strain forY. intermedia.

TL;DR: Assay of the PTS proteins in crr mutants showed that the only component detectably affected was a sugar-specific protein of theTS, Factor IIIG1c, involved in the phsophorylation of glucose (and methyl alpha-glucoside), and the crr gene appears to code for or regulate the synthesis of this protein.
