Enzymatic Verification and Comparative Analysis of Carrageenan Metabolism Pathways in Marine Bacterium Flavobacterium algicola

Carrageenan is the main polysaccharide of red macroalgae and is composed of d -AHG and d -Gal. The carrageenan PUL (CarPUL)-encoded enzymes exist in many marine bacteria for decomposing carrageenan to provide self-growth. Here, the related enzymes in Flavobacterium algicola for metabolizing carrageenan were characterized for describing the catabolic pathways, notably, although the specific polysaccharide hydrolases existed that were like previous studies.
