The malto dextrin uptake operon involves the genes malK, lamB, and malM. The operon's transcription can be activated by having MalT-Maltotriose-ATP DNA-binding transcriptional activator bind to -230.5, -220.5, -74.5, -64.5 or -40.5 bp from the promoter. The operon's transcription can also be activated by CRP-cAMP DNA-binding transcriptional dual regulator binding to -195.5, -166.5, -132.5, or -100.5 bp from the promoter.
