Modular architecture of nucleotide-binding pockets
Recently, modularity has emerged as a general attribute of complex biological systems. This is probably because modular systems lend themselves readily to optimization via random mutation followed by natural selection. Although they are not traditionally considered to evolve by this process, biological ligands are also modular, being composed of recurring chemical fragments, and moreover they e...
متن کاملRsiteDB: a database of protein binding pockets that interact with RNA nucleotide bases
We present a new database and an on-line search engine, which store and query the protein binding pockets that interact with single-stranded RNA nucleotide bases. The database consists of a classification of binding sites derived from protein-RNA complexes. Each binding site is assigned to a cluster of similar binding sites in other protein-RNA complexes. Cluster members share similar spatial a...
متن کاملThe modular architecture of protein-protein binding interfaces.
Protein-protein interactions are essential for life. Yet, our understanding of the general principles governing binding is not complete. In the present study, we show that the interface between proteins is built in a modular fashion; each module is comprised of a number of closely interacting residues, with few interactions between the modules. The boundaries between modules are defined by clus...
متن کاملModular Architecture
The benefits of modularity are a low redesign effort and the possibility of interchanging between different layers depending on the requirements of the application. This makes the node very versatile and adaptable. Modularity reduces redesign, as each module is not started from scratch, and cost when the work environment changes. The concept is to have different implementations of each layer to...
متن کاملFast prediction and visualization of protein binding pockets with PASS
PASS (Putative Active Sites with Spheres) is a simple computational tool that uses geometry to characterize regions of buried volume in proteins and to identify positions likely to represent binding sites based upon the size, shape, and burial extent of these volumes. Its utility as a predictive tool for binding site identification is tested by predicting known binding sites of proteins in the ...
