Laminarinase, member of the glycosyl hydrolase family 16. Laminarinase, also known as glucan endo-1,3-beta-D-glucosidase, is a glycosyl hydrolase family 16 member that hydrolyzes 1,3-beta-D-glucosidic linkages in 1,3-beta-D-glucans such as laminarins, curdlans, paramylons, and pachymans, with very limited action on mixed-link (1,3-1,4-)-beta-D-glucans.

glycosyl hydrolase family 16. The O-Glycosyl hydrolases are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A glycosyl hydrolase classification system based on sequence similarity has led to the definition of more than 95 different families inlcuding glycosyl hydrolase family 16. Family 16 includes lichenase, xyloglucan endotransglycosylase (XET), beta-agarase, kappa-carrageenase, endo-beta-1,3-glucanase, endo-beta-1,3-1,4-glucanase, and endo-beta-galactosidase, all of which have a conserved jelly roll fold with a deep active site channel harboring the catalytic residues.

Streptomyces laminarinase-like, member of glycosyl hydrolase family 16. Proteins similar to Streptomyces sioyaensis beta-1,3-glucanase (laminarinase) present in Actinomycetales as well as Peziomycotina. Laminarinases belong to glycosyl hydrolase family 16 and hydrolyze the glycosidic bond of the 1,3-beta-linked glucan, a major component of fungal and plant cell walls and the structural and storage polysaccharides (laminarin) of marine macro-algae. Members of the GH16 family have a conserved jelly roll fold with an active site channel.
