6. Endoglucanase and Mannanase from Blue Mussel, Mytilus edulis: Purification, Characterization, Gene and Three Dimensional Structure
Sammanfattning : Two polysaccharide-degrading enzymes (endo-1,4-D-glucanase and β-mannanase) from blue mussel, Mytilus edulis, have been purified to homogeneity using a combination of several chromatographic steps. Each enzyme has been characterized with regard to its molecular weight, isoelectric point, pH and temperature stability, pH and temperature optimum and substrate specificity. LÄS MER
7. Exploring glycoside hydrolase family 5 (GH5) enzymes
Sammanfattning : In 1990, the classification of carbohydrate-active enzymes (CAZymes) was introduced by the scientist Bernard Henrissat. According to sequence similarity, these enzymes were separated into families with conserved structures and reaction mechanisms. LÄS MER
8. Structural Studies of Three Glycosidases
Sammanfattning : Glycosidases hydrolyse the glycosidic bond in carbohydrates. Structural studies of three glycosidases with different substrate specificities are presented in this work.Dextranase catalyzes the hydrolysis of α-1,6-glycosidic linkage in dextran polymers. LÄS MER
9. Enzymatic conversion of β-mannans: Analysing, evaluating and modifying transglycosylation properties of glycoside hydrolases
Sammanfattning : Retaining glycoside hydrolases are enzymes that catalyse the breakdown down of glycans through hydrolysis. Due to the double-replacement mechanism of the retaining glycoside hydrolases (GHs), which form an intermediate with part of the glycan covalently attached to the enzyme, some GHs are able to catalyse synthesis reactions called transglycosylation.
