The suitability of synchrotron radiation circular dichroism spectroscopy (SRCD) for studying interactions between the tricyclic peptide inhibitor siamycin I and the intact FsrC membrane sensor kinase in detergent micelles has been established. In the present study, tertiary structural changes demonstrate that inhibitor binding occurs at a different, non-overlapping site to the native ligand, GBAP.

We report on the case of a girl with type 1 Gaucher’s disease, treated from age 9 to 15 with highdose enzyme replacement therapy. This treatment did not avert the development of an extensive mutilating hepatic fibrosis warranting a liver transplantation, which was followed by death. In some cases of Gaucher’s disease, alternative strategies such as fractionated or further increased ERT, gene th...

Mutations in β-glucocerebrosidase (encoded by GBA1) cause Gaucher disease (GD), a lysosomal storage disorder, and increase the risk of developing Parkinson disease (PD). The pathogenetic relationship between the two disorders is unclear. Here, we characterised Ca(2+) release in fibroblasts from type I GD and PD patients together with age-matched, asymptomatic carriers, all with the common N370S...

Lewy body disease (LBD) development is enhanced by mutations in the GBA gene coding for glucocerebrosidase (GCase). The mechanism of this association is thought to involve an abnormal lysosomal system and we therefore sought to evaluate if lysosomal changes contribute to the pathogenesis of idiopathic LBD. Analysis of post-mortem frontal cortex tissue from 7 GBA mutation carriers with LBD, 5 GB...

Gaucher's disease is a rare inherited inborn error of metabolism caused by mutations in the gene encoding the lysosomal enzyme glucocerebrosidase, GBA. Glucocerebrosidase is involved in the metabolism of the lipid metabolism-derived substrate, glucocerebroside. Accumulation of glucocerebroside substrate in macrophages, as a result of loss of enzyme function, leads to the formation of Gaucher ce...

Gaucher disease is an autosomal recessive disorder, characterized by decreased levels of the lysosomal enzyme glucocerebrosidase. This deficiency results in a decreased breakdown of this glycosphingolipid glucocerebroside, which accumulates in the lysosomes of the monocyte-macrophage system. It is the most common form of sphingolipidosis. Clinically, the principle signs of Gaucher's disease are...
