merlin ’s path from organism genome to enzymatic homology data. The BLAST search (configured with the parameters presented above) was performed in the first stage of the homology data inference (STEP A). Specific information for each gene homologues, such as identifiers or scores, is parsed and saved in STEP B. Finally, the Entrez protein web services are used to retrieve the metabolic information, such as EC numbers or taxonomy in STEP C.
