BASys: Bacterial Annotation System

Home | About | Documentation | Examples | Login

Welcome to BASys!
BASys (Bacterial Annotation System) is a web server that performs automated, in-depth annotation of bacterial genomic (chromosomal and plasmid) sequences. It accepts raw DNA sequence data and an optional list of gene identification information and provides extensive textual and hyperlinked image output. BASys uses more than 30 programs to determine nearly 60 annotation subfields for each gene, including gene/protein name, GO function, COG function, possible paralogues and orthologues, molecular weight, isoelectric point, operon structure, subcellular localization, signal peptides, transmembrane regions, reactions, and pathways. The textual annotations and images that are provided by BASys can be generated in approximately 16 hours for an average bacterial chromosome (5 Megabases. 5000 genes), or approximately 350 coding regions per hour.
Some sample chromosome maps and annotations created by BASys are available in the Examples.

There are currently 42 submissions in the queue.

BASys has annotated 5,214 submissions and 4,056,188 coding regions since April 04, 2005.

BASys will store annotations on the server for 180 days.

Gene Identification (Optional)

BASys can predict protein coding regions from the genome sequence using Glimmer (default),
or
choose one of the following:

FASTA Nucleotide Coding Regions File

You can supply BASys with a FASTA-formatted Nucleotide Coding Regions File using the NCBI ".ffn" format. BASys requires the definition line be in the format ">identifier:cstart-end name "
where:

identifier (optional) a unique gene identifier,
c specifies that the coding sequence is on the complementary strand,
start specifies the start location on the direct strand of the genome
end specifies the end location on the direct strand of the genome, and
name (optional) specifies the gene name.

BASys Gene Identification Table


You can supply BASys with a TAB-delimited Gene Identification Table like so: START END STRAND IDENTIFIER name 332 805 + 11496586 mob 4373 4257 - 11496606

GeneMark HMM Gene Identification Table


If you are submitting phage genomes, you can supply BASys with the gene predictions obtained from the GeneMark HMM website. GeneMark HMM predictions look like this: Predicted genes Gene Strand LeftEnd RightEnd Gene Class # Length 1 - 1 2115 2115 1 2 + 2128 2394 267 1 3 - 2378 2656 279 1 4 + 3225 3440 216 1 5 + 3528 3779 252 1 6 - 3879 5702 1824 1 7 - 5840 6220 381 1
