NMR spectroscopy can provide information on many different aspects of proteinligand interactions-not only structural but also dynamic, kinetic and thermodynamic (Jardetzky and Roberts, 1981; Feeney and Birdsall,
In order for this to occur the protein substrate must be expressed, fold, cofactors inserted, other accessory proteins folded, assembled and associate prior to interaction with the translocase. This process is guided by system specific chaperones (REMPs) that act as an escort of the Tat system ...
(i.e., antagonist) competes for the same target-binding site. These control mechanisms that regulate the signaling interaction network are similar to those that control other biomolecular interactions such as enzyme–substrate interactions. However, altering the affinity of an assembly by covalent ...
but current approaches have exclusively concentrated on addressing one of these issues, overlooking the similarity of both tasks in reflecting the relationship of protein sequences towards substrate structures. A statistical approach has been proposed to inferKmvalues across...
In many cases, the concomitant protein–enzyme and protein–cosubstrate interactions can mask modification-specific thermal stability changes of the substrates. This problem is addressed in our method of System-wide Identification of Enzyme Substrates by Thermal Analysis (SIESTA). SIESTA identifies specifi...
Between these two limits are various interactions of intermediate strength which account for the cohesion and yet mobility of liquids, and for the existence of specific biologically important complexes such as those of antibody-antigen, hormone-receptor and enzyme-substrate....
(Bayer, 2004; Schoffelen and van Hest2012). Compared with other co-localization techniques, protein scaffolds have some advantages. First, the minimum distance between the active site on the protein scaffold allows for effective substrate channels, because metabolic intermediates are more likely to ...

Enprocal is a high-protein micro-nutrient rich formulated supplementary food designed to meet the nutritional needs of the frail elderly and be delivered to them in every day foods. We studied the potential of Enprocal to improve gut and immune health using simple and robust bioassays for gut ce...
biochemical methods in detail, leading to the hypothesis of a three-step model of the cleavage process. The first step is the formation of the enzyme-substrate (ES) complex (Fig.1, species 1), and it has been proposed that the enzyme may use active site interactions to orient the β-...
