In enzymology, a 2'-hydroxybiphenyl-2-sulfinate desulfinase (EC 3.13.1.3) is an enzyme that catalyzes the chemical reaction
- 2'-hydroxybiphenyl-2-sulfinate + H2O 2-hydroxybiphenyl + sulfite
Thus, the two substrates of this enzyme are 2'-hydroxybiphenyl-2-sulfinate and H2O, whereas its two products are 2-hydroxybiphenyl and sulfite.
This enzyme belongs to the family of hydrolases, specifically those acting on carbon-sulfur bonds. The systematic name of this enzyme class is 2'-hydroxybiphenyl-2-sulfinate sulfohydrolase. Other names in common use include gene dszB-encoded hydrolase, 2-(2-hydroxyphenyl) benzenesulfinate:H2O hydrolase, DszB, HBPSi desulfinase, 2-(2-hydroxyphenyl) benzenesulfinate sulfohydrolase, HPBS desulfinase, 2-(2-hydroxyphenyl)benzenesulfinate hydrolase, 2-(2'-hydroxyphenyl)benzenesulfinate desulfinase, and 2-(2-hydroxyphenyl)benzenesulfinate desulfinase.

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.
