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.
氧化亚铁硫杆菌的无细胞提取物含有水解酶，这些酶能从5'-磷酸腺苷硫酸或3'-磷酸腺苷5'-磷酸硫酸中裂解出硫酸根。在孵育混合物中加入磷酸盐或腺嘌呤核苷酸可能会抑制这些硫酸酯酶的活性。3'-磷酸腺苷5'-磷酸硫酸及其直接分解产物3'-磷酸腺苷5'-磷酸的降解速度比5'-磷酸腺苷硫酸慢。
