Purification and characterization of a novel cold adapted fungal glucoamylase
BACKGROUND Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature. Unfortunately, most amylases isolated from bacteria and filamentous fungi have optimal activity above 45 °C and low pH. For example, the most commonly used industrial glucoamylases, a type of amylase t...
متن کاملProcessive endoglucanases mediate degradation of cellulose by Saccharophagus degradans.
Bacteria and fungi are thought to degrade cellulose through the activity of either a complexed or a noncomplexed cellulolytic system composed of endoglucanases and cellobiohydrolases. The marine bacterium Saccharophagus degradans 2-40 produces a multicomponent cellulolytic system that is unusual in its abundance of GH5-containing endoglucanases. Secreted enzymes of this bacterium release high l...
متن کاملCarbohydrase Systems of Saccharophagus degradans Degrading Marine Complex Polysaccharides
Saccharophagus degradans 2-40 is a γ-subgroup proteobacterium capable of using many of the complex polysaccharides found in the marine environment for growth. To utilize these complex polysaccharides, this bacterium produces a plethora of carbohydrases dedicated to the processing of a carbohydrate class. Aiding in the identification of the contributing genes and enzymes is the known genome sequ...
متن کاملDiscovery and characterization of cadherin domains in Saccharophagus degradans 2-40.
Saccharophagus degradans strain 2-40 is a prominent member of newly discovered group of marine and estuarine bacteria that recycle complex polysaccharides. The S. degradans 2-40 genome codes for 15 extraordinary long polypeptides, ranging from 274 to 1,600 kDa. Five of these contain at least 52 cadherin (CA) and cadherin-like (CADG) domains, the types of which were reported to bind calcium ions...
متن کاملCrystallization and preliminary X-ray analysis of neoagarobiose hydrolase from Saccharophagus degradans 2-40.
Many agarolytic bacteria degrade agar polysaccharide into the disaccharide unit neoagarobiose [O-3,6-anhydro-alpha-L-galactopyranosyl-(1-->3)-D-galactose] using various beta-agarases. Neoagarobiose hydrolase is an enzyme that acts on the alpha-1,3 linkage in neoagarobiose to yield D-galactose and 3,6-anhydro-L-galactose. This activity is essential in both the metabolism of agar by agarolytic ba...
