Presentation

HOGENOM is a database of homologous genes from fully sequenced organisms (bacteria, archeaea and eukarya) , structured under ACNUC sequence database management system.

It allows to select sets of homologous genes among species, and to visualize multiple alignments and phylogenetic trees.

It is as well possible to search for orthologous genes in a wide range of taxons.

Thus HOGENOM is particularly useful for comparative sequence analysis, phylogeny and molecular evolution studies. More generaly, HOGENOM gives an overall view of what is known about a peculiar gene family. Note that HOGENOM is splitted into two databases: HOGENOM contains the protein sequences while HOGENOMDNA contains the nucleotide sequences. Protein sequences of HOGENOM have been generated by translating the CDS of HOGENOMDNA and using associated cross-references to generate the annotations.
