Galactose-6-sulfurylase
Encyclopedia
In enzymology, a galactose-6-sulfurylase is an enzyme
that catalyzes
the chemical reaction
This enzyme belongs to the family of transferase
s, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is D-galactose-6-sulfate:alkyltransferase (cyclizing). Other names in common use include porphyran sulfatase, galactose-6-sulfatase, and galactose 6-sulfatase.
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...
- Eliminates sulfate from the D-galactose 6-sulfate residues of porphyran, producing 3,6-anhydrogalactose residues.

Transferase
In biochemistry, a transferase is an enzyme that catalyzes the transfer of a functional group from one molecule to another . For example, an enzyme that catalyzed this reaction would be a transferase:In this example, A would be the donor, and B would be the acceptor...
