ATP-Sulfurylase From Penicillivm Chbysogenum. I. Purification and Characterization

A purified ATP-sulfurylase from Peniaillium ehrysogenum has been purified 945-fold by a procedure involving heat treatment, ammonium sulfate fractionation, anion exchange chromatography, and gel filtration, with overall recovery of activity 47%.

Adenosine 5'-triphosphate-sulfurylase in corn roots and its partial purification.

The data suggest that at least the first reaction in sulfate reduction might proceed as effectively in roots as in shoots, and in the presence of exogenous pyrophosphatase, the enzyme from roots exhibited specific activities as high as those obtained with the leaf enzyme.

Purification and characterization of ATP sulfurylase from the extremely thermophilic archaebacterial sulfate‐reducer, Archaeoglobus fulgidus

ATP sulfurylase (sulfate adenylyltransferase, EC 2.7.7.4) was isolated from the recently described extremely thermophilic sulfate-reducing archaebacterium Archaeglobus fulgidus. The enzyme was

Purification and properties of the ATP sulphurylase of rat liver.

Species specific release of sulfate from adenylyl sulfate by ATP sulfurylase or ADP sulfurylase in the green sulfur bacteria Chlorobium limicola and Chlorobium vibrioforme

High activities of ATP sulfurylase were found in the soluble protein fraction of two Chlorobium limicola strains, whereas ADP sulfuryLase was absent, and the stoichiometry of the reaction was proven.

METABOLIC REGULATION OF ADENOSINE TRIPHOSPHATE SULFURYLASE IN YEAST

The sulfate-reducing pathway in yeast appears to be regulated at its first step both by feedback inhibition (by sulfide) and by repression (by methionine).

Enzymatic synthesis of adenosine-5'-phosphosulfate.

The effect of vitamin A and other dietary constituents on the activity of adenosine triphosphate sulphurylase.

It is concluded that, when the effect of protein deprivation on ATP sulphurylase is separated from theeffect of vitamin A deficiency, a lowering of the enzyme activity caused by the vitamin deficiency is demonstrable.

Studies on metabolism of vitamin A. 2. Enzymic synthesis and hydrolysis of phenolic sulphates in vitamin-A-deficient rats.

It is shown here that in vitamin-A-deficient rats there is a slight increase in the urinary excretion of inorganic sulphate, whereas that of the ethereal sulphates is markedly reduced, and the activity of enzymes responsible for the sulphurylation of phenols is markedly lowered in the tissues of the deficient rats.
