FunctionInvertase (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]. For details in Hebrew see Invertase (Hebrew). RelevanceINV is used in the food industry to produce fructose which is sweeter and does not crystallize easily. Structural highlightsThe [3]. |
