1,3-ALPHA-1,4-BETA-D-GALACTOSE-4-SULFATE-3,6-ANHYDRO-D-GALACTOSE-2-SULFATE 4 GALACTOHYDROLASE
Overview
Carrageenans are gel-forming hydrocolloids extracted from the cell walls, of marine red algae. They consist of d-galactose residues bound by, alternate alpha(1-->3) and beta(1-->4) linkages and substituted by one, (kappa-carrageenan), two (iota-carrageenan), or three (lambda-carrageenan), sulfate-ester groups per disaccharide repeating unit. Both the kappa- and, iota-carrageenan chains adopt ordered conformations leading to the, formation of highly ordered aggregates of double-stranded helices. Several, kappa-carrageenases and iota-carrageenases have been cloned from marine, bacteria. Kappa-carrageenases belong to family 16 of the glycoside, hydrolases, which essentially encompasses polysaccharidases specialized in, the hydrolysis of the neutral polysaccharides such as agarose, ...
