Expression

Organism Comment Expression
Escherichia coli addition of nitrate during anaerobic growth represses the expression of dmlA-lacZ about 2.2fold, but the expression is still higher than the expression under aerobic conditions. The presence of glucose during anaerobic growth represses dmlA expression to levels similar to those observed after nitrate addition, suggesting that there is some glucose repression (2.4fold) down
Escherichia coli in a wild-type background, D-malate and meso- and L-tartrate cause high levels of induction of dmlA-lacZ expression (up to 12.3fold). With L-malate, succinate, and D-tartrate there is only weak induction. Induction of dmlA encoding DmlA requires an intact dmlR gene, which encodes DmlR, a LysR-type transcriptional regulator up
Escherichia coli the expression of dmlA-lacZ at high levels is induced under anaerobic conditions in the presence of D-malate and is more than 5fold greater than the expression under aerobic conditions up
