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 ...

Comparison The Kinetics of The Uptake of Sugars From The Draw Solution [PDF]
The present work includes studying the kinetics of the adsorptionof two sugars (maltose and glucose)on activated carbon (GAC) and comparison between them. These sugars are used as draw solution in the forward osmosis process in MOD-SET system(manipulated

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

Structural basis for the mechanism of ABC transporters. [PDF]
The ATP-binding cassette (ABC) transporters are primary transporters that couple the energy stored in adenosine triphosphate (ATP) to the movement of molecules across the membrane.

Stimulation of the Maltose Transporter ATPase by Unliganded Maltose Binding Protein [PDF]
ATP hydrolysis by the maltose transporter (MalFGK(2)) is regulated by maltose binding protein (MBP). Binding of maltose to MBP brings about a conformational change from open to closed that leads to a strong stimulation of the MalFGK(2) ATPase. In this study, we address the long-standing but enigmatic observation that unliganded MBP is also able to ...

Crystal Structure of Thermotoga maritima α-Glucosidase AglA Defines a New Clan of NAD+-dependent Glycosidases [PDF]
Glycoside hydrolase family 4 represents an unusual group of glucosidases with a requirement for NAD(+), divalent metal cations, and reducing conditions. The family is also unique in its inclusion of both alpha- and beta-specific enzymes.

Discovery of an auto-regulation mechanism for the maltose ABC transporter MalFGK2. [PDF]
The maltose transporter MalFGK(2), together with the substrate-binding protein MalE, is one of the best-characterized ABC transporters. In the conventional model, MalE captures maltose in the periplasm and delivers the sugar to the transporter.
