The Binding of Maltose to ‘Virgin’ Maltose‐Binding Protein is Biphasic [PDF]
The biphasic binding properties of the galactose‐binding and maltose‐binding proteins of Escherichia coli may be important in the functioning of these proteins as recognition components of chemoreceptors. However, Richarme and Kepes [Eur. J. Biochem. 45, 127‐133 (1974)] have suggested that the biphasic binding curve of the galactose‐binding protein may

A structural perspective on α-glucan catabolism in oxygenic phototrophs. [PDF]
SUMMARY Starch and glycogen are the main α‐glucan storage polymers in oxygenic photoautotrophs, ensuring metabolic continuity during day/night cycles and environmental stress. Their mobilization requires a suite of catabolic enzymes whose activities are tightly regulated to balance carbon storage with energy demands.

Exploration of multi-state conformational dynamics and underlying global functional landscape of maltose binding protein. [PDF]
An increasing number of biological machines have been revealed to have more than two macroscopic states. Quantifying the underlying multiple-basin functional landscape is essential for understanding their functions. However, the present models seem to be

Substrate induction and glucose repression of maltose utilization by Streptomyces coelicolor A3(2) is controlled by malR, a member of the lacI-galR family of regulatory genes [PDF]
malR of Strepomyces coelicolor A3(2) encodes a homologue of the Lacl/Galr family of repressor proteins, and is divergently transcribed from the malEFG gene cluster, which encodes components of an ATP-dependent transport system that is required for ...

Maltose and maltodextrin utilization by Listeria monocytogenes depend on an inducible ABC transporter which is repressed by glucose. [PDF]
In the environment as well as in the vertebrate intestine, Listeriae have access to complex carbohydrates like maltodextrins. Bacterial exploitation of such compounds requires specific uptake and utilization systems.We could show that Listeria ...

Maltoporins and maltose-binding proteins of Yersinia enterocolitica [PDF]
Two components of the Yersinia enterocolitica maltose transport system, maltoporin (OmpM) and an osmotically shockable periplasmic maltose-binding protein (MBP) were identified. The synthesis of OmpM (apparent Mr 43,000) and transport of maltose into cells of Y. enterocolitica were induced by maltose and maltodextrins.

The Major Soybean Allergen Gly m Bd 28K Induces Hypersensitivity Reactions in Mice Sensitized to Cow's Milk Proteins [PDF]
Reactions to soy have been reported in a proportion of patients with IgE-mediated cow’s milk allergy (CMA). In this work, we analyzed if Gly m Bd 28K/P28, one of the major soybean allergens, is a cross-reactive allergen with cow milk proteins (CMP).

Proteomic analysis of the secretory response of Aspergillus niger to D-maltose and D-xylose [PDF]
Fungi utilize polysaccharide substrates through extracellular digestion catalyzed by secreted enzymes. Thus far, protein secretion by the filamentous fungus Aspergillus niger has mainly been studied at the level of individual proteins and by genome and ...

Synthesis of fluorinated maltose derivatives for monitoring protein interaction by 19F NMR
A novel reporter system, which is applicable to the 19F NMR investigation of protein interactions, is presented. This approach uses 2-F-labeled maltose as a spy ligand to indirectly probe protein–ligand or protein–protein interactions of proteins fused ...
