Secretomics Database Query
As bit of background; I work in a microbiology with C. difficile. I use a gut model to simulate the conditions of the colon, it is inoculated with a human slurry from faeces to populate the model with gut organisms. We can study the populations overtime in a simulated C. difficile infection.
I have been using a proteomics method whereby I can isolate proteins produced from the gut model organisms. These proteins are then passed through LC-MS/MS.
The problem I have is that this environment is very complex and comprises of many different microbial species. There is therefore a great variety of proteins produced, much of the work I have seen has been in single species proteomics.
Is anybody aware of any multispecies bacterial secretomics/proteomics databases I could use to identify my sequences? The proteomics centre that I work with are familiar with identification of human proteins but have not worked with bacterial proteins before. Any suggestions would be very welcome.
