Information on Sequence
Structure and Evolution
This is an update of the third release of ABCISSE (version 3.3).
ABCISSE is a relational database describing the properties and the protein
composition of experimentally investigated ATP-binding cassette (ABC) systems.
In addition, we report complete inventories of the predicted ABC systems
for organisms whose complete genome sequence is known.
In the latter case, ABC proteins and their interacting partners were
identified by comparing the proteomes of these organisms to the full content
of ABCISSE. Systems were reconstructed and sorted in families and subfamilies
according to the phylogenetic and functional classification with was described
in our publications. We predict the polarity of transport,
the substrate specificity and the biological role of these systems.
The database now contains all ABC systems so far identified in the GenBank
database translations on December 2003. The annotation process is manual
and this explains the delay in sequence annotation. To follow the increasing
amount of new genomic sequences, future updates will appear periodically.
