cscB (sucrose permease) for sucrose transport.
Usage and Biology
CscB (sucrose permease) is a sucrose/H+ symporter from E. coli W that relies on an H+ gradient across the cell membrane to transport sucrose, and allows bacteria to take up sucrose [1]. The first study of using CscB as a sucrose exporter in cyanobacteria was reported by Ducat et. al [2] where they showed that Synechococcus elongatus 7942 could export sucrose irreversibly to concentrations of >10 mM without culture toxicity.
The higher pH value in the extracellular medium creates a reversed proton gradient, which enables the engineered cyanobacteria to export sucrose outside the cell [1].
