Metabolic Pathway Builder is a bioinformatics environment dedicated to microbial research.

[citation needed] This covers sequence assembly, mapping, annotation transfer and identification of protein domains, comparative genomics, structural searches, metabolic pathway analysis, modeling and simulation of biological networks.

Genostar's software is platform independent and can thus be used for both Mac OS X, Windows, and Linux.

Metabolic Pathway Builder integrates several methods dedicated to proteic annotation: Genostar's Expression Data Solution (EDS) connects microarray data to genes, gene products and biochemical reactions, based on keywords and annotations.

This software allows to: Genostar's MicroB database consists of genomic, proteic, biochemical and metabolic data from approximately 1100 bacterial and archaeal organis.
