Predicting small ligand binding sites in proteins using backbone structure
MOTIVATION Specific non-covalent binding of metal ions and ligands, such as nucleotides and cofactors, is essential for the function of many proteins. Computational methods are useful for predicting the location of such binding sites when experimental information is lacking. Methods that use structural information, when available, are particularly promising since they can potentially identify n...
متن کاملPredicting in vivo binding sites of RNA-binding proteins using mRNA secondary structure.
While many RNA-binding proteins (RBPs) bind RNA in a sequence-specific manner, their sequence preferences alone do not distinguish known target RNAs from other potential targets that are coexpressed and contain the same sequence motifs. Recently, the mRNA targets of dozens of RNA-binding proteins have been identified, facilitating a systematic study of the features of target transcripts. Using ...
متن کاملPredicting Ca 2 + - binding sites in proteins ( ion binding / molecular recognition /
The coordination shell of Ca2+ ions in proteins contains almost exclusively oxygen atoms supported by an outer shell of carbon atoms. The bond-strength contribution of each ligating oxygen in the inner shell can be evaluated by using an empirical expression successfully applied in the analysis of crystals of metal oxides. The sum of such contributions closely approximates the valence of the bou...
متن کاملMetal Binding Sites in Proteins
Metal ions play a critical role in living systems. About one third of proteins need to bind metal for their stability and/or function. In this review, current sequence based and structure based methods for metal binding site prediction will be presented, with emphasis on the CHED and SeqCHED methods of prediction from apo-protein structures and protein sequences having homologs (even remote) in...
متن کاملThe BKCa Channel's Ca2+-binding Sites, Multiple Sites, Multiple Ions
In this issue, Zeng et al. report results from a series of elegant experiments that, among other contributions, provide new evidence in support of the hypothesis that the BK Ca channel contains two types of high-affinity Ca 2 -binding sites. Those that work with this channel will quickly recognize the significance of these data. To the less well initiated, however, it might seem surprising that...
