Function
function
Positively regulates the transcription of the maltose regulon whose gene products are responsible for uptake and catabolism of malto-oligosaccharides. Specifically binds to the promoter region of its target genes, recognizing a short DNA motif called the MalT box.
Activity regulation
Activated by ATP and maltotriose, which are both required for DNA binding.
Features
Showing features for binding site, dna binding.
