The
plasmid
database
PLSDB
This resource is database of plasmids by NCBI.
Plasmids can be explored and filtered using the
browsing
tables.
Nucleotide sequences can be
searched
in the database by either using
Mash
for longer sequences (e.g. contigs or long reads), or by using
BLASTn
for shorter sequences, e.g. genes.

What is new in v. 2024_05_31_v2?
We've optimized our infrastructure to provide a better user experience:
12,465 new records
Enhanced data retrieval
. Incorporation of
Archaea
kingdom and unification of Biosample attributes.
Example
.
Identical Plasmids
. Preservation of biologically relevant contextual information during the removal of duplicates.
Example
.
Improved Disease and Ecosystem Classification
. Expanded classifications now include environmental ecosystems (e.g., aquatic, terrestrial) and enriched information on host-associated ecosystems (e.g., Homo sapiens, gastrointestinal system, fecal).
Example
.
Plasmid Features Annotation
. Comprehensive annotation of functional structures, including protein-coding genes, MOB typing, antimicrobial resistance genes, and biosynthetic gene clusters.
Example
.
Webserver redesign
. To accommodate these improvements, the webserver of PLSDB has also been reconstructed, resulting in decreased response times and enhanced visualization of features while ensuring that users have access to a more efficient and user-friendly interface.
