and nbsf Structural word with Lpmax and nbsf Intense superfamily-specific word with a precision for a Swiss-Prot annotation: intense structural words are topic to additional examination to validate their structural or functional role.Regad et al. BMC Bioinformatics , : http:biomedcentral-Page ofexample, when the annotation is “binding”, the secondlevel annotation indicates the ligand form. The precision is defined as the proportion of fragments encoded by a structural word which might be annotated by a given annotation thinking about the two levels of annotation. A structural word with higher precision is mentioned to become functional. As a way to take into account the sparsity of Swiss-Prot annotations, we set a permissive threshold of precision. The sensitivity (also known as recall) is defined by the proportion of a given annotation order CB-5083 that’s covered by a structural word. To compute the sensitivity, we retained only annotations extracted from protein loops, annotations noticed in regular secondary structures regions are discarded. In complement to Swiss-Prot annotations, that are of high quality but far from full, we used many external tools to identify putative functional motifs. The Catalytic Website Atlas (CSA) database documents enzyme active websites and catalytic residues in enzymes of known D structure. It identifies the residues straight inved in the enzymatic reaction. The Ligplot application enables the identification of interactions in between proteins and ligands, by providing schematic diagrams of protein-ligand interactions from a offered PDB file. The REP software program is utilized to predict repeat regions from protein sequences. This software program makes use of an iterative homology-based repeat locating technique. The SitePredict software http:sitepredict. org is applied to predict nucleotide and calciumbinding web sites. SitePredict is often a machine learning technique determined by diverse residue properties, such as the spatial clustering of residue forms and conservation during eution. Only residues having a score aboveare deemed to be inved in the binding internet site.Figure Definitions and illustration of coverage rates. We thought of a set of seven words of four structural letters (SPBD, UQRS, RBTU, DOCI, ZPCD, PCDU, DUGO), grouping sevenresidue fragments. Let us look at that these words and their occurrence are examples and not the true occurrences inside the PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/24465392?dopt=Abstract data set. From this set of words, we focused on three words, named restricted set and presented in red inside a, grouping seven sevenresidue fragments. Several coverage prices were calculated for these words. A: word coverage, the fraction of structural words included in the restricted set. B: fragment coverage, the fraction of fragments encoded by words in the restricted set. C: loop-length coverage, the fraction of residues in loops covered by words in the restricted set. D: protein coverage, the fraction of proteins containing a minimum of among the words from the restricted set.proportion of fragments encoded by the structural word that contain the identified structural motif.Validation in the functional function of intense superfamilyspecific wordsThe functional implication of superfamily-specific structural words was explored employing the biological annotations in the Swiss-Prot database extracted from the annotation data set. The comparison of structural words with Swiss-Prot annotations extracted from annotation data set is restricted to the protein.
