Motivation

Collection of all known microbial interactions

data integration: known interactions are spread over several interaction databases users need to query several datasets to gather all interactions

small scale reference interactions: ‘true positive’ reference set of microbial interactions curated from the literature

publication resource: for JCVI’s experimental protein-protein interactions

To answer questions like

Does my protein of interest have known interaction partners?

Is my favourite interaction conserved in another species?

Have my interacting proteins been co-crystalized in a 3D structure?

Can I trust this experimental interaction result? ...
