Maltose (/ ˈ m ɔː l t oʊ s / [2] or / ˈ m ɔː l t oʊ z / [3]), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond. In the isomer isomaltose , the two glucose molecules are joined with an α(1→6) bond.

Maltose-binding protein (MBP) is a part of the maltose/maltodextrin system of Escherichia coli, which is responsible for the uptake and efficient catabolism of maltodextrins. It is a complex regulatory and transport system involving many proteins and protein complexes. MBP has an approximate molecular mass of 42.5 kilodaltons.
In bacterial genetics, the mal regulon is a regulon - or group of genes under common regulation - associated with the catabolism of maltose and maltodextrins.The system is especially well characterized in the model organism Escherichia coli, where it is classically described as a group of ten genes in multiple operons whose expression is regulated by a single regulatory protein, malT.

In enzymology, a maltose synthase (EC 2.4.1.139) is an enzyme that catalyzes the chemical reaction 2 alpha-D-glucose 1-phosphate + H 2 O ⇌ {\displaystyle \rightleftharpoons } maltose + 2 phosphate Thus, the two substrates of this enzyme are alpha-D-glucose 1-phosphate and H 2 O , whereas its two products are maltose and phosphate .
In enzymology, a maltose epimerase (EC 5.1.3.21) is an enzyme that catalyzes the chemical reaction alpha-maltose ⇌ {\displaystyle \rightleftharpoons } beta-maltose Hence, this enzyme has one substrate , alpha-maltose , and one product , beta-maltose .
Hydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides so as to remove successive maltose units from the non-reducing ends of the chains This enzyme acts on starch , glycogen and related polysaccharides and oligosaccharides producing beta- maltose by an inversion.
