What is MiST?
The Microbial Signal Transduction database contains the signal transduction proteins for bacterial and archaeal genomes (2,457 complete and 5,181 draft). These are identified using various domain profiles that directly or indirectly implicate a particular protein in participating in signal transduction.

- In v2.2, the protein ids have changed. We are working on mapping the old ids to the new ids. Until this is complete, please use the previous version, http://v2-1.mistdb.com if you need to work with the old ids.
- An alternative, more stable approach is to only store references to sequences using the gene locus.

- New version 2.2 - badly needed genome update; majority of new genomes are incomplete. Many genomes available for various strains of the same species.
- Minor usability improvements (e.g. the list of genomes and the taxonomy browser is much more interactive and dynamic.)
- No more genome metadata (phenotype, gram-stain, disease, etc.); NCBI no longer provides this information in an easily accessible format.
