Abstract:Abstract(#br)Chromatin-associated DNA topoisomerase I activity was measured in human diploid fibroblasts during in vitro aging. No diilerence was detected as a function of cell age in the nicking and the closing activities of the DNA-unwinding enzyme. The capacity of type-I topoi...

Abstract:Directed evolution was applied to the α- l- arabinofuranosidase from Thermobacillus xylanilyticus to confer better transglycosylation ability, particularly for the synthesis of benzyl α- l -arabinofuranosyl-(1,2)-α- d -xylopyranoside, starting from p -nitrophenyl α- l -arabi...

Abstract:Abstract(#br)Random mutagenesis was performed on the α- l -arabinofuranosidase of Thermobacillus xylanilyticus in order to enhance its ability to perform transarabinofuranosylation using natural xylo-oligosaccharides as acceptors. To achieve this goal, a two-step, high-throu...

Abstract:Abstract(#br)The activity and stability of a β-glycosidase ( Thermus thermophilus) and two α-galactosidases ( Thermotoga maritima and Bacillus stearothermophilus) were studied in different hydrophilic ionic liquid (IL)/water ratios. For the ILs used, the glycosidases showed ...

Abstract:Abstract(#br)The oxidative coupling of methane has been studied in the presence of lamellar perovskites Bi 2 O 2 (A n-1 B n O 3n+1 ) belonging to Aurivillius phases. These materials are selective and stable in the OCM reaction. Moreover, their substitution in perovskite (A) or oc...

Abstract:Abstract(#br)Alkoxyamino derivatives of oligosaccharides have been synthesized by enzymatic synthesis using a glycosynthase and a transglycosidase. The chemoselective assembly of unprotected oligosaccharides bearing glucose at the reducing end with N -alkyl- O -benzylhydroxylamin...

Abstract:Abstract(#br)The exopolysaccharide (EPS) HE800 is a marine-derived polysaccharide (from 8 × 10 5 to 1.5 × 10 6 g mol −1 ) produced by Vibrio diabolicus and displaying original structural features close to those of glycosaminoglycans. In order to confer new biological activit...

Abstract:Abstract(#br)Antibodies represent an interesting protein framework on which catalytic functions can be grafted. In previous studies, we have reported the characterization of the catalytic antibody 4B2 obtained on the basis of the “bait and switch” strategy which catalyzes tw...

Abstract:Abstract(#br)The role of microbial activity on the alteration of steel containers used for nuclear waste disposal is increasingly discussed. In this work we isolated and identified sulphate-reducing bacteria (SRB) in the Callovo–Oxfordian clay rock studied as a potential hos...
