Post-translational protein modification by tyrosine sulfation has an important role in extracellular protein-protein interactions. The protein tyrosine sulfation reaction is catalysed by the Golgi enzyme called the tyrosylprotein sulfotransferase. To date, no crystal structure is available for tyrosylprotein sulfotransferase. Detailed mechanism of protein tyrosine sulfation reaction has thus re...
To date, the laboratory has cloned seven unique human sulfotransferases; five aryl sulfotransferases (HAST1, HAST2, HAST3, HAST4 and HAST4v), an estrogen sulfotransferase and a dehydroepiandrosterone sulfotransferase. The cellular distribution of human aryl sulfotransferases in human hepatic and extrahepatic tissues has been determined using the techniques of hybridization histochemistry and im...
Running Title desulfo-Glucosinolate sulfotransferases from Arabidopsis thaliana SUMMARY The phytotoxin coronatine is a structural analog of octadecanoid signaling molecules which are well known mediators of plant defense reactions. In order to isolate novel coronatine-regulated genes from Arabidopsis thaliana, differential mRNA display was performed. Transcript levels of CORI-7 (coronatine indu...
A thermostable phenol sulfotransferase, SULT1A1, has been implicated in numerous detoxification and bioactivation pathways; however, little is known regarding its endogenous function or its putative role in mediating risk for human environmental disease. A simple endpoint colorimetric assay is described that can be used for rapid phenotyping of SULT1A1 activity in human populations. The assay u...
Methyl-hydroxylated metabolites of the potent carcinogen, 7,12-dimethylbenz[a]anthracene (DMBA), namely, 7-hydroxymethyl-12-methylbenz[a]anthracene (7-OH-DMBA), 7-methyl-12-hydroxymethylbenz[a]anthracene (12-OH-DMBA) and 7,12-dihydroxymethylbenz[a]anthracene (7,12-diOH-DMBA), were examined as substrates for sulfotransferase bioactivation in different human tissue cytosols. Hepatic cytosols, whi...
NDST1 was recently proposed as a candidate gene for autosomal recessive intellectual disability in two families. It encodes a bifunctional GlcNAc N-deacetylase/N-sulfotransferase with important functions in heparan sulfate biosynthesis. In mice, Ndst1 is crucial for embryonic development and homozygous null mutations are perinatally lethal. We now report on two additional unrelated families wit...
The metabolic activities and tissue binding of estrone (E1) and estrone sulfate (E1S) on futile cycling were examined. Desulfation of E1S in the 9000g supernatant fraction (S9) of periportal (PP) and perivenous (PV) rat hepatocytes were of similar V (2.9 +/- 1.0 and 2.4 +/- 0.9 nmol/min/mg of S9 protein), K (30.4 +/- 8.3 and 34.8 +/- 6.6 microM), and desulfation intrinsic clearances (V/K of 77 ...
