Sulfur reductase
Encyclopedia
In enzymology, a sulfur reductase is an enzyme
that catalyzes
the chemical reaction
of reduction of elemental sulfur or polysulfide to hydrogen sulfide.
This enzyme belongs to the family of oxidoreductase
s. The systematic name of this enzyme class is (donor):sulfur oxidoreductase.
Enzyme
Enzymes are proteins that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates...

Catalysis
Catalysis is the change in rate of a chemical reaction due to the participation of a substance called a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. A catalyst may participate in multiple chemical transformations....

Chemical reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity...
