The ACLAME database is dedicated to the collection, analysis and classification of sequenced mobile genetic elements (MGEs, in particular phages and plasmids). Classifications are available at various levels of organization. At the gene/protein level, families group similar sequences that are expected to share the same function. Families of four or more proteins are manually assigned with a functional annotation using the GeneOntology and the locally developed ontology MeGO dedicated to MGEs. At the genome level, evolutionary cohesive modules group sets of protein families shared among MGEs. At the population level, networks display the reticulate evolutionary relationships among MGEs.
BASys (Bacterial Annotation System) is a tool for automated annotation of bacterial genomic (chromosomal and plasmid) sequences including gene/protein names, GO functions, COG functions, possible paralogues and orthologues, molecular weights, isoelectric points, operon structures, subcellular localization, signal peptides, transmembrane regions, secondary structures, 3-D structures, reactions, and pathways.
The CGView Server generates graphical maps of circular genomes that can be used to visualize sequence conservation in the context of sequence features, imported analysis results, open reading frames and base composition plots. The server uses BLAST to compare the primary sequence of up to three genomes or sequence sets, aiding in the identification of conserved genome segments, instances of horizontal transfer or visualization of genome segments from newly obtained sequence reads.
DNASU is a central repository for plasmid clones and collections. DNASU currently stores and distributes over 130,000 plasmids including over 45,000 human and mouse plasmids, full genome collections from numerous organisms, and the protein expression plasmids from the Protein Structure Initiative (PSI).
The integrated microbial genomes (IMG) system serves as a community resource for comparative analysis of publicly available genomes in a comprehensive integrated context. IMG contains both draft and complete microbial genomes integrated with other publicly available genomes from all three domains of life, together with a large number of plasmids and viruses. IMG provides tools and viewers for analyzing and reviewing the annotations of genes and genomes in a comparative context.
The IRESite presents carefully curated experimental evidence of many eukaryotic viral and cellular internal ribosome entry site (IRES) regions. The IRESite tool provides biologically meaningful information regarding the IRESs and their experimental background (including annotation of IRES secondary structures and IRES trans-acting factors). RNA secondary structures and for searching through the structures currently stored in the database can also be done.
Web server that automatically generates and annotates circular plasmid maps. The tool has: a built in set of features that can be displayed (ie. RE sites, tags, ORFs, etc.); allows users to define custom features to display; contains a library of commonly used plasmids; and, generates nice looking images in a variety of output formats.
taveRNA hosts three RNA web services: alteRNA, inteRNA and pRuNA. alteRNA is an alternative to many RNA folding methods. inteRNA predicts the joint secondary structure of two RNA sequences. pRuNA is an database pruning method which given a query RNA returns only a few ncRNAs as potential regulators.
T7 RNAi Oligo Designer (TROD) aids in the design of DNA oligonucleotides for short interfering RNA (siRNA) synthesis with T7 RNA polymerase. It takes an input of a cDNA sequence and outputs a list of DNA oligos for ordering.
WEB-THERMODYN analyzes DNA sequences and computes the DNA helical stability. This tool can be used to predict sites of low helical stability present at regulatory regions for transcription and replication.
