Virtual Identification of Essential Proteins Within the Protein Interaction Network of Yeast [PDF]
Topological analysis of large scale protein-protein interaction networks (PINs) is important for understanding the organisational and functional principles of individual proteins. The number of interactions that a protein has in a PIN has been observed to be correlated with its indispensability.

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

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 ...

Length, Protein-Protein Interactions, and Complexity [PDF]
The evolutionary reason for the increase in gene length from archaea to prokaryotes to eukaryotes observed in large scale genome sequencing efforts has been unclear. We propose here that the increasing complexity of protein-protein interactions has driven the selection of longer proteins, as longer proteins are more able to distinguish among a larger ...

Development of an electrochemical maltose biosensor [PDF]
In this work, electrochemical maltose biosensors based on mutants of the maltose binding protein (MBP) are developed. A ruthenium II complex (Ru II ), which is covalently attached to MBP, serves as an electrochemical reporter of MBP conformational ...

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.

ProNet DB: A proteome-wise database for protein surface property representations and RNA-binding profiles [PDF]
The rapid growth in the number of experimental and predicted protein structures and more complicated protein structures challenge users in computational biology for utilizing the structural information and protein surface property representation. Recently, AlphaFold2 released the comprehensive proteome of various species, and protein surface property ...

Merkel cell polyomavirus large T antigen disrupts lysosome clustering by translocating human Vam6p from the cytoplasm to the nucleus [PDF]
Merkel cell polyomavirus (MCV) has been recently described as the cause for most human Merkel cell carcinomas. MCV is similar to simian virus 40 (SV40) and encodes a nuclear large T (LT) oncoprotein that is usually mutated to eliminate viral replication ...

Solution NMR studies of periplasmic binding proteins and their interaction partners
Periplasmic binding proteins (PBPs) are a crucial part of ATP-binding cassette import systems in Gram-negative bacteria. Central to their function is the ability to undergo a large-scale conformational rearrangement from open-unliganded to closed ...
