Dual transcriptional inhibition of glutamate and alanine racemase is synergistic in .

Synergistic interactions between chemical inhibitors, whilst informative, can be difficult to interpret, as chemical inhibitors can often have multiple targets, many of which can be unknown. Here, using multiplexed transcriptional repression, we have validated that the simultaneous repression of glutamate racemase and alanine racemase has a synergistic interaction in . This confirms prior observations from chemical interaction studies and highlights the potential of targeting multiple enzymes involved in mycobacterial cell wall synthesis.
