Abstract
Porphyran, a polysaccharide composed of red algae, is a source of a multifunctional oligosaccharide material and raw biomass with various physiological activities. The glycolysis of porphyrans into oligosaccharides through various porphyranases is an approach for obtaining high-quality and promising alternative resources. In this study, porphyran was extracted from Porphyra yezoensis and used as a research substrate. We also established an efficient hydrolysis method using an enzymatic complex obtained through cohesin-dockerin interactions that degrade natural polysaccharides. The cohesion-dockerin interaction is designed to genetically bind the dockerin module to the end of an existing enzyme and then attach the cohesin module to obtain a protein complex. The designed protein complex has been shown to further increase the activity on the substrate, which can be considered a useful method to obtain efficient oligosaccharides or monosaccharides through hydrolysis of red algae for bioresources.
