Enhancing the stability and the reusability of ulva polysaccharide lyase (UPL) is crucial for the efficient production of reducing sugars from ulva polysaccharides, which are vital for their broad applications in functional foods. In this study, we innovatively developed a self-immobilized UPL by fusing the enzyme with ferritin, leading to the ...

Klebsiella K14 capsular polysaccharide was degraded by a bacteriophage-borne enzyme to afford oligosaccharides A-C which were studied by one- and two-dimensional n.m.r. spectroscopy. A and B were the repeating-unit hexasaccharide and pyruvylated hexasaccharide, respectively, while C was a dodecasaccharide.

Influence of the culture conditions on extracellular lyase activity related to K5 polysaccharide
Biotechnology Letters, 2000The K5 capsular polysaccharide antigen of some Escherichia coli strains is the non-sulphated precursor in heparin biosynthesis. It is composed by two components, 16 000 and 1500 Da, whose ratio depends on the activity of the extracellular form of a lyase synthesized by the same K5 producer strain.

Two Alginate Lyases from Polysaccharide Lyase Family 44 Exhibited Diversity in Substrate Specificity
Journal of Agricultural and Food ChemistryAlginate lyases are important tools for alginate biodegradation and oligosaccharide preparation. This study characterized the two alginate lyases, Aly44An and Aly44Pa, from the newly constructed polysaccharide lyase family 44 (PL44). Aly44An exhibited the highest enzyme activity and conversion efficiency for polyM and also showed activity for alginate ...
