Overview of the MetaPro-IQ approach. The human or mouse gut microbial gene catalog is freely downloadable online [20, 24]. For the first two steps of the database search, each of the samples was processed individually. The identified protein sequences for all the samples were then combined to generate a refined small study-specific sub-database, which will be used for the final-step quantitative analysis using MaxQuant
