What is "bisphosphate"

n. (context organic chemistry English) A diphosphate, especially a compound with two phosphate groups attached to a sugar residue

Bisphosphate may refer to:

• (ribulose-bisphosphate carboxylase)-lysine N-methyltransferase (EC 2.1.1.127), an enzyme that catalyzes the chemical reaction S-adenosyl-L-methionine + [ribulose-1,5-bisphosphate carboxylase]-lysine S-adenosyl-L-homocysteine + [ribulose-1,5-bisphosphate carboxylase]-N6-methyl-L-lysine
• 3'(2'),5'-bisphosphate nucleotidase (EC 3.1.3.7), an enzyme that catalyzes the chemical reaction adenosine 3',5'-bisphosphate + HO adenosine 5'-phosphate + phosphate
• Fructose 1,6-bisphosphate, fructose sugar phosphorylated on carbons 1 and 6
• Fructose 2,6-bisphosphate (or fructose 2,6-diphosphate), abbreviated Fru-2,6-P2, a metabolite which allosterically affects the activity of the enzymes phosphofructokinase 1 (PFK-1) and fructose 1,6-bisphosphatase (FBPase-1) to regulate glycolysis and gluconeogenesis
• Fructose-2,6-bisphosphate 2-phosphatase (EC 3.1.3.46), an enzyme that catalyzes the chemical reaction beta-D-fructose 2,6-bisphosphate + HO D-fructose 6-phosphate + phosphate
