glycogen storage disease type ii/アルブミン

Soluble polymers of rat (or human) albumin and alpha-1,4-glucosidase are prepared using the cross-linking agent glutaraldehyde. The resulting polymer has an average molecular weight of 800 000 indicating an average composition of 12 albumin molecules for each enzyme molecule. Compared with an

BACKGROUND In adult glycogen storage disease type II (GSDII), a single-gene mutation causes reduction of the lysosomal enzyme acid alpha-glucosidse. This produces a chronic proximal myopathy with respiratory involvement. Enzyme replacement treatment (ERT) has recently become available and is

1. Albumin activates human liver acid alpha-glucosidase (alpha-D-glucoside hydrolase, EC 3.2.1.20). From the Arrhenius plot, pH-dependence and Lineweaver-Burk plots it can be concluded that this activation is not only due to stabilisation of the enzyme, but also influences the enzymatic activity. It
