The exopolysaccharide produced byStreptococcus thermo-philus8S in reconstituted skimmed milk is a heteropolysac-charide containing D-galactose, D-glucose, D-ribose, and N-acetyl-D-galactosamine in a molar ratio of 2:1:1:1. Furthermore, the polysaccharide contains one equivalent of a novel open chain nononic acid constituent, 3,9-dideoxy-D-threo-D-altro-nononic acid, ether-linked viaC-2 toC-6 of an additionalD-glucose per repeating unit.

Novel chromogenic substrates for endo-b-galactosidase were designed on the basis of the structural features of keratan sulfate. Galb1-4GlcNAcb1-3Galb1-4GlcNAcb-pNP (2),which consists of two repeating units ofN-acetyl-lactosamine,was synthesized enzymatically by consecutive additions of GlcNAc and Gal residues top-nitrophenyl b-N-acetyllactosaminide. In a similar manner,Glc-NAcb1-3Galb1-4GlcNAcb-pNP (1),GlcNAcb1-3Galb1-4Glcb-pNP (3),Galb1-4GlcNAcb1-3Galb1-4Glcb-pNP (4), Galb1-3GlcNAcb1-3Galb1-4Glcb-pNP (5),and Galb1-6GlcNAcb1-3Galb1-4Glcb-pNP (6) were synthesized as analogues of2.

Streptococcus mitisstrain SK598, which represents a sub-group of biovar 1, possesses a unique variant of the C-polysaccharide found in the cell wall of all strains of Streptococcus pneumoniaeand in some strains ofS. mitis. This newvariant lacks the cholinemethyl groups in contrast to the previously characterized forms of C-polysaccharide, whichall containone or two choline residues per repeat. The following structure of the repeating unit of the SK598 polysaccharide was established: where AAT is 2-acetamido-4-amino-2,4,6-trideoxy-D-galactose....

The activity of the digestiveb-glycosidase fromSpodoptera frugiperda (Sfbgly50, pH optimum 6.2) depends on E399 (pKa¼4.9; catalytic nucleophile) and E187 (pKa¼7.5; catalytic proton donor). Homology modelling of the Sfbgly50 active site confirms that R97 and Y331 form hydrogen bonds with E399. Site-directed mutagenesis showed that the substitution of R97 bymethionine or lysine increased the E399 pKa by 0.6 or 0.8 units, respectively, shifting the pH optima of these mutants to 6.5.

E2020 (R,S)-1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]-methyl)piperidine hydrochloride isa piperidine-based ace-tylcholinesterase (AChE) inhibitor that was approved for the treatment of Alzheimer’s disease in the United States. Structure-activity studiesof thisclassof inhibitorshave indicated that both the benzoyl containing functionality and the N-benzylpiperidine moiety are the key featuresfor binding and inhibition of AChE.

The SUMO proteins are a class of small ubiquitin-like modifiers. SUMO is attached to a specific lysine side chain on the target protein via an isopeptide bond with its C-terminal glycine.Thereareat least fourSUMOproteins in humans, which are involved in protein trafficking and tar- geting. A truncated human SUMO-2 protein that contains residues 9–93 was expressed inEscherichia coliand crystal- lized in two different unit cells, with dimensions of a ¼b¼ 75.25 A ˚ ,c¼29.17 A ˚ and a¼b¼74.96 A ˚ ,c¼33.23 A ˚ , both belonging to the rhombohedral space groupR3.

Ana-amylase (TVA II) from Thermoactinomyces vulgaris R-47 efficiently hydrolyzesa-1,4-glucosidic linkages of pullulan to produce panose in addition to hydrolyzing starch. TVA II also hydrolyzesa-1,4-glucosidic linkages of cyclodextrins anda-1,6-glucosidic linkages of isopanose. To clarify the basis for this wide substrate specificity of TVA II, we soaked 4 3 -a-panosylpanose (4 3 -P2) (a pullulan hydro-lysate composed of two panosyl units) into crystals of D325N inactive mutated TVA II.

A novel long-chain acyl-CoA thioesterase fromAlcaligenes faecalishas been isolated and characterized. The protein was extracted from the cells with 1mNaCl, which required 1.5-fold, single-step purification to yield near-homogeneous preparations. In solution, the protein exists as homo-meric aggregates, of mean diameter 21.6 nm, consisting of 22-kDa sub-units.
