Methylumbelliferyl-tetra-N-acetylchitotetraoside hydrolase activity was increased 53- to 484-fold in plasma from Gaucher disease patients and no activator could be found. High activity was also measured in other lysosomal storage diseases including K

1. A very easy fluorescent micromethod is described to measure leukocyte N-acetyl-alpha-D-glucosaminidase in human leukocytes. The method presents the following advantages: possibility to measure low activity due to prolonged linearity, very moderate

We have applied a method using the fluorigenic substrate benzoloxycarbonyl-Arg-Arg-amido-4-methylcoumarin to measure cathepsin B, a thiol proteinase, in homogenates of human leukocytes. Data like pH optimum, stability, influence of thiol groups and e

We have further studied some characteristics of human plasma specific chitinase by making use of the fluorescent substrate methylumbelliferyl-tetra-N-acetyl-beta-D-chitotetraoside (MU-TACT). The enzyme is also active towards the substrates MU-di-N-ac

A novel endoglucosaminidase, originally described by Den Tandt et al. [Int. J. Biochem. 20 (1988), 713-719] and bearing the provisional name MU-TACT hydrolase, was purified from human serum 56,000-fold by means of ammonium sulphate precipitation, ani

1. 1. In human plasma, an enzyme is present which hydrolyzes 4-methylumbelliferyl-tetra-N-acetylchitotetraoside. The function of this enzyme is unknown. 2. 2. We have examined whether hyaluronidase, neutral endoglucosaminidase, N- acetyl -β- d - hex

Using methylumbelliferyl-N-acetyl-beta-D-glucosaminide-6-sulphate as a substrate hexosaminidase A activity was measured in leukocyte homogenates with a one-step method without the need of thermoinactivation. According to the buffer system used--aceta
