Mutations in alpha-glucosidase cause accumulation of glycogen in lysosomes, resulting in Pompe disease, a lysosomal storage disorder. Small molecule chaperones that bind to enzyme proteins and correct the misfolding and mistrafficking of mutant proteins have emerged as a new therapeutic

Lysosomal degradation plays a crucial role in the metabolism of biological macromolecules supplied by autophagy. The regulation of the autophagy-lysosome system, which contributes to intracellular homeostasis, chemoresistance, and tumor progression, has recently been revealed as a promising therapeutic approach for

Pyrococcus furiosus laminarinase (LamA, PF0076) is an endo-glycosidase that hydrolyzes beta-1,3-glucooligosaccharides, but not beta-1,4-gluco-oligosaccharides. We studied the specificity of LamA towards small saccharides by using 4-methylumbelliferyl beta-glucosides with different linkages. Besides endo-activity, wild-type LamA has some exo-activity, and catalyzes the
