Grouped By:  Matching UniProtKB accession

UniProtKB description:  Hydrolyzes 1,4-beta linked polysaccharide backbones of mannans. Has high activity toward locust bean gum (PubMed:18579426, PubMed:25082572). Also active toward konjac and beta-1,4-mannan. Hydrolyzes mannotetraose (M4) and mannopentaose (M5) to mannobiose (M2) and mannotriose (M3) with a little production of mannose (M1). Hydrolyzes beta-1,4-mannan to M2, M3 and M4. Hardly hydrolyzes M2 and M3. Does not hydrolyze p-nitrophenyl-beta-D-mannopyranoside, gua-gum, carboxymethyl cellulose, soluble starch or laminarin (PubMed:18579426).
