Abstract

For the past one decade, there has been considerable explosion of interest in searching novel regulatory elements in the intergenic region between the protein coding regions. The microbial genomes are the most exploited in terms of intergenic (noncoding) regions due to its less complexity. We think, the increasing pace of genome sequencing calls for a tool which will be useful for the extraction of intergenic regions. IntergenicS (Intergenic Sequence) is a tool which can extract the intergenic regions of microbial genomes at NCBI. All the unannotated regions between annotated protein coding genes and noncoding RNA genes can be extracted. It also deals with the calculation of GC base composition of the intergenic regions. This will be a useful tool for the analysis of noncoding regions of both bacterial and archael genomes.
