Purification and characterization of 3'-phosphoadenosine-5'-phosphosulfate:GalCer sulfotransferase from human renal cancer cells.
Honke K., Yamane M., Ishii A., Kobayashi T., Makita A.

We have purified 3'-phosphoadenosine-5'-phosphosulfate:GalCer sulfotransferase [EC 2.8.2.11] from a human renal cancer cell line SMKT-R3 through a combination of affinity chromatographies using galactosylsphingosine, 3',5'-bisphosphoadenosine and heparin as ligands. The purified sulfotransferase showed a specific activity of 1.2 mumol/min/mg, which is 300 times more than the highest activity among the enzyme preparations purified so far from other sources. Homogeneity of the purified sulfotransferase was supported by the facts that the enzyme preparation showed a single protein band with an apparent molecular mass of 54 kDa on reducing SDS-PAGE and that protein bands coincided with the enzyme activity on both native PAGE and nonreducing SDS-PAGE. GalCer was the best acceptor for the purified enzyme. LacCer, GalAAG, and GalDG were also good acceptors. GlcCer, Gg3Cer, Gg4Cer, Gb4Cer, and nLc4Cer did serve as acceptors although the relative activities were low. On the other hand, the enzyme could not act on Gb3Cer, which possesses alpha-galactoside at the nonreducing terminus. Neither galactose nor lactose served as an acceptor. These observations suggest that the sulfotransferase prefers beta-glycoside, especially beta-galactoside, at the nonreducing termini of sugar chains attached to a lipid moiety. << Less

Association of elevated sulfatides and sulfotransferase activities with human renal cell carcinoma.

Lactosylceramide sulfate and galactosylceramide sulfate were found to increase markedly in human renal cell carcinoma (adenocarcinoma) as compared to uninvolved tissue. Activities of two sulfotransferases toward galactosylceramide and lactosylceramide as substrates were significantly elevated in the carcinoma compared to the uninvolved tissue resulting in enhanced synthesis of the two sulfatides in the carcinoma. The elevation of the two sulfotransferases was parallel in most tumors, suggesting that the same enzyme is responsible for the enhanced synthesis of two sulfatides. No consistent difference in the activity of arylsulfatase A, which desulfates the two sulfatides, was observed between the carcinoma and uninvolved tissue. Both the present and previous results show that the increased synthesis of the sulfatide(s) due to elevated sulfotransferase activity could be a biochemical characteristic common to adenocarcinomas derived from different tissues. << Less
