Function
Invertase (INV) catalyzes the hydrolysis of sucrose into glucose and fructose[1]. 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[2].
- Extracellular INV catalyzes the cleavage of the transport sugar sucrose released into the app-last[3]
- Alkaline INV is a tetramer which catalyzes the cleavage of sucrose[4]
- DNA INV Gin is found in bacteriophage Mu and catalyses the recombination between repeat sequences in vivo and in vitro[5]
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 of INV contains the catalytic residues Asp and Glu[6].
