Davis L. Martinec/Sandbox 4eqv

General Description

4EQV is 469 kDa invertase(SInv) first isolated from Saccharomyces cerevisiae. SInv catalyzes the hydrolysis of sucrose into fructose and glucose, thus making it an essential enzyme to plants and other organisms, such as honey bees^[1]. Invertase also lends itself to industry and is extensively used fermentation, where yeast are employed to process sugar into ethanol.

Yeast invertase was first isolated in 1860 by Berthelot , but had been alluded to by Dubrunfaut in 1847^[2].
