Function

MANA_CRYAT 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).^[1] ^[2]

Publication Abstract from PubMed

Endo-beta-1,4-d-mannanase from the Antarctic springtail, Cryptopygus antarcticus (CaMan), is a cold-adapted beta-mannanase that has the lowest optimum temperature (30 degrees C) of all known beta-mannanases. Here, we report the apo- and mannopentaose (M5) complex structures of CaMan. Structural comparison of CaMan with other beta-mannanases from the multicellular animals reveals that CaMan has an extended loop that alters topography of the active site. Structural and mutational analyses suggest that this extended loop is linked to the cold-adapted enzymatic activity. From the CaMan-M5 complex structure, we defined the mannose-recognition subsites and observed unreported M5 binding site on the surface of CaMan. Proteins 2014; 82:3217-3223.
