Mutation of conserved residues in the laminarinase Lam1092 increases the antioxidant activity of the laminarin product hydrolysates.

Abstract excerpt

Laminarinases from the glycoside hydrolase 16 (GH16) family are hydrolases that break β-1,3-glycosidic bonds in laminarin, which is the major storage polysaccharide present in brown algae or microalgae. We explored a laminarinase from the marine Flavobacteriaceae species Tamlana sp. PT2-4 at the structural and functional levels. Based on a homology model of Lam1092-substrate interactions, the large active groove...
