GalU Expression Construct

GalU (BBa_K901004) under control of the LacI promoter (BBa_J04500): galU codes for UDP-Glucose phosphorylase, an E. coli enzyme that produces UDP-glucose.

This expression construct is part of a 3 enzyme system designed to enhance the production and secretion of monosaccharide sugars in Synechococcus elongatus. This system is comprised of InvA (BBa_K901003), Galu, and Glf (BBa_K901008).

GalU codes for UDP-glucose phosphorylase. This is an enzyme from E. coli that produces UDP-glucose. The presence of UDP-glucose enhances the native production of the disaccharide sucrose in S. elongatus in response to salt shock.

Sucrose is then cleaved into glucose and fructose by Invertase A and secreted from the cell via the membrane bound transport protein Glf. These monosaccharides are sufficient nutriment for E. coli and will be used to feed a culture of engineered cells designed to produce high levels of acetic acid.
