The Gemina system provides an integrated investigative and geospatial surveillance system connecting pathogens, pathogen products and disease anchored on the taxonomic ID of the pathogen and host to identify the breadth of hosts and diseases known for these pathogens, to identify the extent of outbreak locations, and to identify unique genomic regions with the DNA Signature Insignia Detection Tool.
The GeneMark family of programs employ Markov models and are specifically tuned for gene prediction for sequences from prokaryotes, viral genomes and eukaryotes.
The Genotyping tool at the NCBI identifies the genotype (or subtype) of viral sequences by using a sliding window approach to BLAST analysis against reference sequences for different viral subtypes. Results are shown as a graphical output plotting the top-scoring genotype. An alignment tool is also available.
Influenza Virus Resource presents data obtained from the NIAID Influenza Genome Sequencing Project as well as from GenBank, combined with tools for flu sequence analysis and annotation. In addition, it provides links to other resources that contain flu sequences, publications and general information about flu viruses.
The NCBI Influenza Virus Sequence Annotation Tool is a web application for user-provided sequences. It can predict protein sequences encoded by an input flu sequence and produce a feature table that can be used for sequence submission to GenBank.
The PhEVER database provides accurate evolutionary and phylogenetic information to analyse the nature of virus-virus and virus-host lateral gene transfers. It is a database of homologous families both (i) between sequences from different viruses and (ii) between viral sequences and sequences from cellular organisms. It offers a clustering of proteins into homologous families containing at least one viral sequences, as well as alignments and phylogenies for each of these families.
ViralORFeome 1.0 is a database and management system that provides an integrated set of bioinformatic tools to clone viral ORFs in the Gateway(R) system. ViralORFeome provides a convenient interface to navigate through virus genome sequences, to design ORF-specific cloning primers, to validate the sequence of generated constructs and to browse established collections of virus ORFs. ViralORFeome has been designed to manage all possible variants or mutants of a given ORF so that the cloning procedure can be applied to any emerging virus strain. A subset of plasmid constructs generated with ViralORFeome platform has been tested with success for heterologous protein expression in different expression systems at proteome scale.
