Knowledge of toxins, virulence factors, and antibiotic
resistance genes is essential for bio-defense applications aimed at
identifying “functional” signatures for characterizing emerging
or engineered pathogens. Whereas genetic signatures identify a
pathogen, functional signatures identify what a pathogen is capable
of. To facilitate rapid identification of sequences and
characterization of genes for signature discovery, we have collected
all publicly available, organized sequences representing known toxins,
virulence factors, and antibiotic resistance genes in one convenient
database, which we believe will be of use to the general bio-defense
research community.
MvirDB currently integrates DNA and protein sequence information from Tox-Prot, SCORPION, the PRINTS database of virulence factors, VFDB, TVFac, Islander, ARGO, CONUS, KNOTTIN, a subset of VIDA
and sequences derived by means of literature searches. Entries in MvirDB are hyperlinked back to their original sources. A blast tool allows the user to blast against all DNA or protein sequences in MvirDB, and a browser tool allows the user to search the database to retrieve virulence factor descriptions, sequences, and classifications, and to download sequences of interest. MvirDB has an automated weekly update mechanism. Each protein sequence in MvirDB is annotated using our fully automated protein annotation system, MannDB, and is linked to that system’s browser tool.
How to use MvirDB
1. MvirDB can be searched using the virulence browser tool. Once a
nce a
selection has been made, the user can navigate through MvirDB and can download sequences of interest.
2. A blast tool allows the user to blast a sequence of interest
against MvirDB to pull up related entries.
