Discovering Domains Mediating Protein Interactions
Background: Protein-protein interactions do not provide any direct information regarding the domains within the proteins that mediate the interactions. The majority of proteins are multi domain proteins and the interaction between them is often defined by the pairs of their domains. Most of the former studies focus only on interacting domain pairs. However they do not consider the in...
متن کاملHyperpolarized Water to Study Protein-Ligand Interactions.
The affinity between a chosen target protein and small molecules is a key aspect of drug discovery. Screening by popular NMR methods such as Water-LOGSY suffers from low sensitivity and from false positives caused by aggregated or denatured proteins. This work demonstrates that the sensitivity of Water-LOGSY can be greatly boosted by injecting hyperpolarized water into solutions of proteins and...
متن کاملProtein-Protein Interactions Involved in Water Transport in Cotton Roots
Down-regulation of aquaporin genes in plant roots in response to water-deficit and salt stress has been reported in many systems including corn, rice, and cotton. Since aquaporins passively aid water movement, we speculate the down-regulation of aquaporin transcripts is a means to reduce the hydraulic conductivity of roots in situations when the osmotic gradient favors water efflux. However, po...
متن کاملRole of water mediated interactions in protein-protein recognition landscapes.
The energy landscape picture of protein folding and binding is employed to optimize a number of pair potentials for direct and water-mediated interactions in protein complex interfaces. We find that water-mediated interactions greatly complement direct interactions in discriminating against various types of trap interactions that model those present in the cell. We highlight the context depende...
متن کاملWater-Protein Interactions: The Secret of Protein Dynamics
Water-protein interactions help to maintain flexible conformation conditions which are required for multifunctional protein recognition processes. The intimate relationship between the protein surface and hydration water can be analyzed by studying experimental water properties measured in protein systems in solution. In particular, proteins in solution modify the structure and the dynamics of ...
