Notes

[back to top]


Activated by maltotriose and ATP to form active oligomers. Signal transduction ATPases with numerous domains (STAND) protein. ATP hydrolysis is not required for transcription activation (Richet, 1989), but is required to recycle back to the inactive form, which has ADP, not ATP bound (Marquenet, 2007). MalY (Clausen, 2000; Schreiber, 2000), MalK (Reyes, 1988; Panagiotidis, 1998; Bohm, 2002) and Aes (Joly, 2002) negatively regulate MalT activity by binding and blocking maltotriose activation. MalT is required for phage lambda sensitivity.[4]
