Expression
Expression on EC 1.1.1.83 - D-malate dehydrogenase (decarboxylating)
Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
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)
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
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
