This absence of annotated genes within one thousand base pairs is relatively unusual within bacteria.
About 15% of annotated genes (2,054) involve the overlap of mRNAs on opposite strands.
Primers for the 14% unsuccessful products were redesigned and synthesized, so that essentially all of the annotated genes were successfully amplified.
We identified a total of 1,941 clusters, representing about 14% of annotated genes, which met all of the above criteria.
The current database version, At cis DB 1.0, consists of promoter sequences of 29,388 annotated genes.
Nearly 4% of the annotated genes are located in head-to-head direction sharing bi-directional promoters of length less than 500 nt.
A bioinformatics analysis has shown that processed pseudogenes can be inserted into introns of annotated genes and be incorporated into alternatively spliced transcripts.
HomoloGene is a system for automated detection of homologs among the annotated genes of several completely sequenced eukaryotic genomes.
First, in some cases, the asd RNA is not in the 5' untranslated region of any annotated gene.
Each annotated gene, after it has been entered into the database, is subjected to BLASTP searching against all other genes already in the database.
