Uduwela and colleagues have revealed that arylsulfatase from Pseudomonas was able to enhance the activity of steroid sulfatase [51], which is capable of catalyzing sulfated steroid precursors to the free steroid, and Pseudomonas has been reported in other estrogen-related diseases, such as endometriosis [52], which is also consistent with our findings. Here, STS is linked to endometriosis.
