Arylsulfatase A in pseudodeficiency
Human Genetics, 1984Arylsulfatase A (ASA) is found to be deficient in healthy individuals (pseudo arylsulfatase A deficiency) who usually show in vitro ASA levels in the range of metachromatic leukodystrophy patients. The in vitro properties of ASA in pseudodeficiency were studied in cultured fibroblasts.

Deficient glycosylation of arylsulfatase A in pseudo arylsulfatase-A deficiency
Molecular and Cellular Biochemistry, 1990Deficient arylsulfatase-A activity is diagnostic of a neurodegenerative human lysosomal storage disease, metachromatic leukodystrophy. Paradoxically, similar enzyme deficiency also occurs in normal individuals, who are known as being pseudo arylsulfatase-A deficient. We showed previously that this phenotype is associated with a structural gene mutation

Arylsulfatase A pseudodeficiency in Chinese
Human Genetics, 1996Arylsulfatase A (ASA) pseudodeficiency was found to be much rarer in Taiwan than in most western countries (2.5% versus 7.3%-20% carrier rate). The linkage of two mutations (A2725G and A1788G) in the pseudodeficiency allele was preserved in Chinese, and A2725G did not occur alone.

Diagnosis of arylsulfatase A deficiency
American Journal of Medical Genetics, 1992AbstractMetachromatic leukodystrophy (MLD) is a neurologically devastating autosomal recessive disorder in humans associated with deficient arylsulfatase A activity. However, clinically normal individuals described as being pseudo‐arylsulfatase‐A deficient also demonstrate the same deficiency.

A library of Pseudoalteromonas carrageenovora arylsulfatase mutants was constructed by introducing random mutagenesis using error-prone PCR. After screening, one mutant strain was obtained whose arylsulfatase had improved thermal stability. Protein sequence analysis revealed one amino acid substitution of H260L.

Arylsulfatase Activity of Soils
Soil Science Society of America Journal, 1970Abstract The detection of arylsulfatases (enzymes that hydrolyze aryl sulfates) in soils is reported, and a simple method of assaying soil arylsulfatase activity is described. This method involves colorimetric estimation of the p ‐nitrophenol released by arylsulfatase ...

Arylsulfatase des menschlichen Harns
Archives of Biochemistry and Biophysics, 1957Zusammenfassung 1. 1. Die Harn-Sulfatase lasst sich in 100-fache Anreicherung in der Acetonfallung gut nachweisen, es kann auf diese Weise die Reaktionszeit auf zwei Stunden verkurzt werden, besonders wenn man als Substrat einen organischen Ester der Schwefelsaure verwendet, der sich durch gute Spaltbarkeit auszeichnet, wie es beim p -Nitro ...

Arylsulfatase in coelomocytes ofHolothuria polii
Experientia, 1988Holothuria polii coelomocytes possess arylsulfatase enzymes. Two pH optima were found for arylsulfatase activity in cell lysate preparations, one at pH 5.0 and the other at pH 5.8. Both increased after injection of zymosan particles or formalinized sheep red blood cells (fSR-BC), indicating an active role of the enzymes during phagocytosis of ...
