CC -!- FUNCTION: Positively regulates the transcription of the maltose regulon
CC whose gene products are responsible for uptake and catabolism of malto-
CC oligosaccharides. Specifically binds to the promoter region of its
CC target genes, recognizing a short DNA motif called the MalT box.
CC {ECO:0000255|HAMAP-Rule:MF_01247}.
CC -!- ACTIVITY REGULATION: Activated by ATP and maltotriose, which are both
CC required for DNA binding. {ECO:0000255|HAMAP-Rule:MF_01247}.
CC -!- SUBUNIT: Monomer in solution. Oligomerizes to an active state in the
CC presence of the positive effectors ATP and maltotriose.
CC {ECO:0000255|HAMAP-Rule:MF_01247}.
CC -!- SIMILARITY: Belongs to the MalT family. {ECO:0000255|HAMAP-
CC Rule:MF_01247}.
