摘要:Beta-Glucosidase Plays An Important Role In The Degradation Of Cellulose. In This Study,A Novel-Glucosidase Ccbgl1B Gene For A Glycosyl Hydrolase (Gh) Family 1 Enzyme Was Cloned From The Genome Of Cellulosimicrobium Cellulans And Expressed In Escherichia Coli Bl21 Cells. The Sequence Contained An Open Reading Frame Of 1494Bp,Encoded A Polypeptide Of 497Amino Acid Residues. The Recombinant Protein Ccbgl1B Was Purified By Ni Sepharose Fastflow Affinity Chromatography And Had A Molecular Weight Of 57Kda,As Judged By Sds-Page. The Optimum-Glucosidase Activity Was Observed At 55 Degrees C And Ph 6.0. Recombinant Ccbgl1B Was Found To Be Most Active Against Aryl-Glycosides P-Nitrophenyl--D-Glucopyranoside (Pnpglc),Followed By P-Nitrophenyl--D-Galactopyranoside (Pnpgal). Using Disaccharides As Substrates,The Enzyme Efficiently Cleaved-Linked Glucosyl-Disaccharides,Including Sophorose (-1,2-),Laminaribiose (-1,3-) And Cellobiose (-1,4-). In Addition,A Range Of Cello-Oligosaccharides Including Cellotriose,Cellotetraose And Cellopentaose Were Hydrolysed By Ccbgl1B To Produce Glucose. The Interaction Mode Between The Enzyme And The Substrates Driving The Reaction Was Modelled Using A Molecular Docking Approach. Understanding How The Gh1 Enzyme Ccbgl1B From C. Cellulans Works,Particularly Its Activity Against Cello-Oligosaccharides,Would Be Potentially Useful For Biotechnological Applications Of Cellulose Degradation.

摘要:The present invention relates to the use of a low-caloric high-protein nutritional composition for use in the prevention or treatment of a disease or condition in a mammal, which involves muscle decline, as well as to specific low-caloric high-protein nutritional compositions for stimulating muscle protein synthesis in a mammal. In particular, the invention relates to the use of a nutritional composition comprising per 100 kcal: (i) at least about 12 g of proteinaceous matter which comprises at least about 80 weight % of whey protein, relative to the total proteinaceous matter, and which comprises at least about 11 weight % of leucine, relative to the total proteinaceous matter, of which at least about 20 weight % is in a free form, relative to the total leucine, (ii) a source of fat and a source of digestible carbohydrates, for the prevention or treatment of a disease or condition which involves muscle decline in a mammal, especially an elderly mammal, wherein the nutritional composition is administered as 1 to 2 servings daily, each serving comprising between 80 and 200 kcal.
