Quercetin-3-sulfate 3'-sulfotransferase
In enzymology, a quercetin-3-sulfate 3'-sulfotransferase () is an enzyme that catalyzes the chemical reaction
:3'-phosphoadenylyl sulfate + quercetin 3-sulfate \rightleftharpoons adenosine 3',5'-bisphosphate + quercetin 3,3'-bissulfate
Thus, the ...
is an enzyme that uses
3'-phosphoadenylyl sulfate and quercetin 3-sulfate to produce
adenosine 3',5'-bisphosphate
Adenosine 3',5'-bisphosphate is a form of an adenosine nucleotide with two phosphate groups attached to different carbons in the ribose ring. This is distinct from adenosine diphosphate, where the two phosphate groups are attached in a chain to th ...
