Invertase

spinqualitylabelsall models Invertase complex with raffinose (stick model), citrate and sulfate (PDB code 1w2t). Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Invertase (INV) catalyzes the hydrolysis of sucrose into glucose and fructose. INV is produced by bees which use it to make honey from nectar. Cell-wall INV is crucial for metabolism, growth and differentiation in plants. Extracellular INV catalyzes the cleavage of the transport sugar sucrose released into the app-last.For details in Hebrew see Invertase (Hebrew). Relevance INV is used in the food industry to produce fructose which is sweeter and does not crystallize easily. Structural highlights The active site pocket of INV contains the catalytic residues Asp and Glu.
