What is MiST?
The Microbial Signal Transduction database contains the signal transduction proteins for 1,019 complete and 234 draft bacterial and archaeal genomes. These are identified using various domain profiles that directly or indirectly implicate a particular protein in participating in signal transduction.

- Manuscript describing MiST2 has been accepted for publication in the upcoming NAR database issue!!
- Due to limited hardware resources, performing queries (especially against all genomes) is particuarly slow and may result in an internal error page. In the next couple months, we will migrate MiST2 to a dedicated server. This should substantially improve the performance and usability of this site. Thanks for your patience while we make this transition.
- Minor changes: Refseq gene name now displayed alongside all lists of proteins, added missing CheV classification.

- Numerous bug fixes; finished help section last Friday evening.
- Significantly improved the search times (especially when searching the domain architecture). See the search help section to learn how to effectively query MiST2.
