(PS)2 Protein Structure Prediction Server performs automated homology modeling by combining PSI-BLAST, IMPALA, and T-Coffee for template selection and target-template alignment. The final three-dimensional (3D) structure is built using RAMP or MODELLER.
3-Dimensional Structural Superposition (3DSS) is a tool for superposing two or more protein structures that uses RASMOL for visualization; some browser configuration is necessary.
Arabidopsis Co-expression Tool (ACT) is a resource for investigating the co-expression of genes in the NASC/GARNet microarray-based gene expression dataset from Arabidopsis.
Agile Protein Interaction DataAnalyzer (APID) allows you to query protein-protein interactions using a common platform facilitating comparison across different datasets. Currently supported interaction databases are BIND, HPRD, DIP, IntAct, and MINT.
ArchPRED predicts the structure of loop regions in protein structures based on a fragment-search based method. Given a query loop of unknown structure, ArchPRED identifies which loops of know structures are likely to share conformational similarity with the query loop.
Alignment of RNA Tertiary Structures (ARTS) is a method for aligning two nucleic acid structures (RNAs or DNAs) and detecting a-priori unknown common substructures.
Alternative Splicing Prediction (ASPic) can predict alternative splicing of user submitted genes based on comparative analysis of available transcript and genome data from a variety of species. Results include graphical and tabular views of the splicing patterns of full-length mRNA isoforms compatible with the detected splice sites of the genes as well as structural and functional annotations.
AUGUSTUS is a eukaryotic gene prediction tool. It can integrate evidence, e.g. from RNA-Seq, ESTs, proteomics, but can also predict genes ab initio. The PPX extension to AUGUSTUS can take a protein sequence multiple sequence alignment as input to find new members of the family in a genome. It can be run through a web interface, or downloaded and run locally.
Babelomics is a suite of web tools for the functional annotation and analysis of groups of genes in high throughput experiments. Tools include: FatiGO, FatiGOplus, Fatiscan, Gene Set Enrichment Analysis (GSEA), Marmite, and the Tissues Mining Tool (TMT). Other tools include Biocarta pathways, Transfac and a tool de novo functional annotation of sequences.
BActeriocin GEnome mining tooL (BAGEL) identifies putative bacteriocin ORFs (antimicrobial peptides) based on a database containing information about known bacteriocins and adjacent genes involved in bacteriocin activity.
The Bioinformatics Links Directory features curated links to molecular resources, tools and databases. All of the resources are free or available for a nominal fee.
BiologicalNetworks allows retrieval, construction, and visualization of biological networks and allows for the analysis of high-throughput expression data by mapping onto network graphs. BiologicalNetworks queries the PathSys system, a combined database of biological pathways, gene regulatory networks, and protein interaction maps.
Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.
