Rapid degradation of steroid sulfatase in multiple sulfatase deficiency
Biochemical and Biophysical Research Communications, 1986Pulse labeling followed by SDS-PAGE electrophoresis of immunoprecipitated [35S]methionine-labeled steroid sulfatase (STS) gave a single band of molecular weight 65,000 daltons. After a chase period of 18 hours the material appeared as molecular weight approximately 64,000.

The conversion of 5-en-3β-ol steroid sulfates to active hormones has been extensively studied. A preliminary desulfation of the precursors is required to allow their structure 5-ene-3β-ol to be transformed to the con-figuration 4-ene-3-keto present in active hormones.

Estrogen sulfatase is a microsomal enzyme and is ubiquitously distributed in several mammalian tissues, among which the liver, placenta, and endocrine tissues exhibit relatively high activity. Because the major circulating precursors of estrogen are estrone 3-sulfate and dehydroepiandrosterone 3-sulfate, estrogen sulfatase plays an important role not ...

Current Opinion in Genetics & Development, 1997
During the past few years, molecular analyses have provided important insights into the biochemistry and genetics of the sulfatase family of enzymes, identifying the molecular bases of inherited diseases caused by sulfatase deficiencies. New members of the sulfatase gene family have been identified in man and other species using a genomic approach ...

Human glucosamine-6-sulfatase cDNA reveals homology with steroid sulfatase
Biochemical and Biophysical Research Communications, 1988Glucosamine-6-sulfatase is a lysosomal enzyme which degrades glycosaminoglycans and is deficient in mucopolysaccharidosis type IIID. Human liver contains two major active forms of glucosamine-6-sulfatase, form A which has a single 78 kDa polypeptide and form B which has two polypeptides of 48 kDa and 32 kDa.

Developmental regulation of choline sulfatase and aryl sulfatase in Neurospora crassa
Archives of Biochemistry and Biophysics, 1974Abstract Regulation of the synthesis of several enzymes of sulfur metabolism in Neurospora is a function of both metabolic regulation and the genetic control exerted by the cys -3 and scon regulatory genes. Additional control mechanisms appear to regulate the synthesis of choline sulfatase and aryl sulfatase in different developmental stages of ...

Synthesis and sulfatase inhibitory activities of non-steroidal estrone sulfatase inhibitors
The Journal of Steroid Biochemistry and Molecular Biology, 1996About one-third of breast cancers are classified as estrogen-dependent breast cancers. In the past 10 years, numerous reports have suggested the importance of estrone sulfate and estrone sulfatase in regulating the supply of estrogens to these cancers. Estrone sulfatase inhibitors may thus prove to be useful for the treatment of these diseases. Several

Publisher Summary This chapter discusses the sulfatases from Helix pomatia. Sulfate esters are common metabolites, and their characterization can be aided by the use of a homogeneous, or highly purified, sulfatase of broad specificity as a hydrolyzing agent. The highly specific mammalian arylsulfatases are not suitable.

アルドール硫酸もヒドラヂンにより分解される.それ故,ヒドラヂンにより分解される現象は還元糖の硫酸エステルに限らず,還元基を有する多くの硫酸エステルに廣く認められるのであらう.アラビノーゼ硫酸のヒドラヂンによる分解速度を種々の條件の下で測定した.

Evidence is presented indicating that three sulfatase activities towards UDP-N-acetylgalactosamine 4-sulfate, nitrocatechol sulfate, and chondroitin 4-sulfate are functions of the same hen oviduct enzyme. Using chondroitin [35S]sulfate from chick embryo cartilage, it is shown that hydrolysis of ester sulfate by this enzyme is limited to 4-sulfate ...
