Trithionate hydrolase explained

trithionate hydrolase
Ec Number:	3.12.1.1
Cas Number:	115004-90-5
Go Code:	0047401

In enzymology, a trithionate hydrolase is an enzyme that catalyzes the chemical reaction^{[1] [2]}

trithionate + H₂O

\rightleftharpoons thiosulfate + sulfate + 2 H⁺

Thus, the two substrates of this enzyme are trithionate and H₂O, whereas its 3 products are thiosulfate, sulfate, and H⁺.

This enzyme belongs to the family of hydrolases, specifically those acting on sulfur-sulfur bonds. The systematic name of this enzyme class is trithionate thiosulfohydrolase. This enzyme participates in sulfur metabolism.
