The structural gene for arylsulfatase (atsA) of Klebsiella aerogenes was cloned into a pKI212 vector in Escherichia coli. Deletion analysis showed that the atsA gene with the promoter region was located within a 3.2-kilobase cloned segment. In E. coli cells which carried the plasmid, the synthesis of arylsulfatase was repressed by various sources of sulfur; the repression was relieved, in each ...

Little is known about the potential of enzyme activities, which are sensitive to soil properties and management, for the characterization of dust properties. Enzyme activities may be among the dust properties key to identifying the soil source of dust. We generated dust (27 and 7 microm) under controlled laboratory conditions from agricultural soils (0-5 cm) with history of continuous cotton (G...

Exfoliative toxin from Staphylococcus aureus was mitogenic for murine spleen cells. It was primarily active on T lymphocytes but also significantly stimulated B cells from the spleens of nude mice. The mitogenicity was not affected by simple sugar or alpha-methylpyranosides. N-acetylglucosamine and N-acetylgalactosamine inhibited its effect. Exfoliatin was as powerful a mitogen as the enterotox...

Beet vinasse (BV), a green manure constituted by Trifolium pratense L. uncomposted (TP) and composted with beet vinasse (at 1:1 rate, (TP+BV)1, and 2:1 rate, (TP+BV)2) at 10t organic matter ha(-1) rate were applied during a period of four years for purpose of restoration of a Xelloric Calciorthid located near Seville (Guadalquivir Valley, Andalusia, Spain). The effect on the plant cover, soil p...

A rapidly growing, non-photochromogenic acid-fast organism was isolated from a lesion in a 6-month-old pig. The isolate was subsequently identified as Mycobacterium chelonei by its growth rate, but its failure to reduce nitrates, and by being arylsulfatase positive at 3 days.

Molecular alterations associated with arylsulfatase A pseudodeficiency (ASA-PD) were characterized by PCR and restriction endonuclease analysis in a sample of healthy individuals from Brazil. ASA activity was also assayed in all subjects. Two individuals homozygous for the N350S and 1524+95A<--G mutations were detected, corresponding to a frequency of 1.17% (4 of 324 alleles). The individual fr...
