In enzymology, a phosphoadenylylsulfatase (EC 3.6.2.2) is an enzyme that catalyzes the chemical reaction
- 3'-phosphoadenylyl sulfate + H2O adenosine 3',5'-bisphosphate + sulfate
Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and H2O, whereas its two products are adenosine 3',5'-bisphosphate and sulfate.
This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides in sulfonyl-containing anhydrides. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate sulfohydrolase. Other names in common use include 3-phosphoadenylyl sulfatase, 3-phosphoadenosine 5-phosphosulfate sulfatase, PAPS sulfatase, and 3'-phosphoadenylylsulfate sulfohydrolase. This enzyme participates in sulfur metabolism. It employs one cofactor, manganese.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
