                      HOBACGEN Release 7 (May 2000)


     The  new  release  of  HOBACGEN  (the Homologous Bacterial Genes
     Database)  is  now available. Information on the database can be
     accessed at:

     HOBACGEN  is  a  database  system  that contains all the protein
     sequences of bacteria  organized into families. It allows one to
     select  sets  of  homologous genes from bacterial species and to
     visualize multiple alignments and phylogenetic trees.

     The  database contains all sequences of bacteria (eubacteria and
     archeae)  and  yeast  taken  from SWISS-PROT + TrEMBL, with some
     annotation modifications. It contains also all the corresponding
     nucleotide  sequences  from  EMBL. Homologous proteins are clas-
     sified  into  families  and multiple alignments and phylogenetic
     trees are computed for each family.

     This new version of HOBACGEN has been built using sequences from
     SWISS-PROT  38  (+  updates until April 21) and TrEMBL 12. Among
     the  128,293  proteins  used  to build this release, 104,763 are
     from bacteria, 15,025 from archaea, and 6,829 from yeast.
