Abstract

Cyanobacterial KnowledgeBase (CKB) is a free access database that contains the genomic and proteomic information of 74 fully sequenced cyanobacterial genomes belonging to seven orders. The database also contains tools for sequence analysis. The Species report and the gene report provide details about each species and gene (including sequence features and gene ontology annotations) respectively. The database also includes cyanoBLAST, an advanced tool that facilitates comparative analysis, among cyanobacterial genomes and genomes of E. coli (prokaryote) and Arabidopsis (eukaryote). The database is developed and maintained by the Sub-Distributed Informatics Centre (sponsored by the Department of Biotechnology, Govt. of India) of the National Facility for Marine Cyanobacteria, a facility dedicated to marine cyanobacterial research. CKB is freely available at http://nfmc.res.in/ckb/index.html.

The BLAST analysis tool compares sequence within cyanobacterial species and with E. coli and Arabidopsis. It consists of A, B, C, D and E divisions where A: denotes different programs of BLAST tool, B: the sequence input page, C: option to select the individual or an order wise cyanobacterial dataset, D: choice to choose genomes of 74 cyanobacterial genomes fully or only chromosomes or only plasmids for analysis and E: option to choose E. coli and /or Arabidopsis.
