The MalT-dependent and malZ-encoded maltodextrin glucosidase of Escherichia coli can be converted into a dextrinyltransferase by a single mutation.

The Journal of biological chemistry - 3 May 1996

Peist R, Schneider-Fresenius C, Boos W

Abstract excerpt

malZ is a member of the mal regulon. It is controlled by MatT, the transcriptional activator of the maltose system. MalZ has been purified and identified as an enzyme hydrolyzing maltotriose and longer maltodextrins to glucose and maltose. MalZ is dispensable for growth on maltose or maltodextrins. Mutants lacking amylomaltase (encoded by malQ), the major maltose utilizing enzyme, cannot grow on maltose,...
