Glutamine—fructose-6-phosphate transaminase (isomerizing)
Template:Infobox enzyme In enzymology, a glutamine-fructose-6-phosphate transaminase (isomerizing) (Template:EC number) is an enzyme that catalyzes the chemical reaction
- L-glutamine + D-fructose 6-phosphate L-glutamate + D-glucosamine 6-phosphate
Thus, the two substrates of this enzyme are L-glutamine and D-fructose 6-phosphate, whereas its two products are L-glutamate and D-glucosamine 6-phosphate.
This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-glutamine:D-fructose-6-phosphate isomerase (deaminating). This enzyme participates in glutamate metabolism and aminosugars metabolism.
