| Abstract: | The cell-free extracts of Thiobacillus ferrooxidans contain hydrolytic enzymes which cleave sulphate from either adenosine 5′-sulphatophosphate or adenosine 3′-phosphate 5′-sulphatophosphate. These sulphatase activities may be retarded by including either phosphates or adenine nucleotides in the incubation mixtures. Adenosine 3′-phosphate 5′-sulphatophosphate and its immediate breakdown product adenosine 3′-phosphate 5′-phosphate were degraded at slower rates than adenosine 5′-sulphatophosphate. |
