The Detergent-Soluble Maltose Transporter Is Activated by Maltose Binding Protein and Verapamil [PDF]
ABSTRACT The maltose transporter FGK2 complex of Escherichia coli was purified with the aid of a glutathione S -transferase molecular tag. In contrast to the membrane-associated form of the complex, which requires liganded maltose binding protein (MBP) for ATPase activity, the ...

Targets for the MalI repressor at the divergent Escherichia coliK-12malX-malI promoters [PDF]
Random mutagenesis has been used to identify the target DNA sites for the MalI repressor at the divergent Escherichia coli K-12 malX-malI promoters. The malX promoter is repressed by MalI binding to a DNA site located from position -24 to position -9 ...

Role of Denaturation in Maltose Binding Protein Translocation Dynamics [PDF]
We present a computational study on the driven transport of the Maltose Binding Protein (MBP) across nanochannels in the framework of coarse-grained modeling. The work is motivated by recent experiments on voltage-driven transport of MBP across nanopores exploring the influence of denaturation on translocation pathways. Our simplified approach allows a

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.

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser. [PDF]
G-protein-coupled receptors (GPCRs) signal primarily through G proteins or arrestins. Arrestin binding to GPCRs blocks G protein interaction and redirects signalling to numerous G-protein-independent pathways.

Background: The fermentation conditions of recombinant maltose-binding protein fused to neutrophil-activating protein (rMBP-NAP) of Helicobacter pylori were optimized from Escherichia coli TB1 with varying medium, inoculum age and size, time, inducer, pH

The detection and quantification of protein–protein interactions (PPIs) is a crucial technique that often involves the use of recombinant proteins with fusion protein tags, such as maltose-binding protein (MBP) and glutathione-S-transferase (GST).
