Functional categorization of open reading frames within human milk. The percent of ORFs assigned to each functional category is shown. Using the “Hierarchical Classification” tool within MG-RAST, 41,352 ORFs were submitted, 33,793 were annotated and assigned to a functional category (maximum e-value of 1x10^-5, minimum identity of 60%, and minimum alignment length of 15 aa). Three categories of genes (stress, virulence, carbohydrates) are expanded on the right to demonstrate the diverse capabilities of milk-derived DNA sequences.
