Gut microbiota DPP4-like enzymes are increased in type-2 diabetes and contribute to incretin inactivation

Abstract excerpt

BACKGROUND: The gut microbiota controls broad aspects of human metabolism and feeding behavior, but the basis for this control remains largely unclear. Given the key role of human dipeptidyl peptidase 4 (DPP4) in host metabolism, we investigate whether microbiota DPP4-like counterparts perform the same function. RESULTS: We identify novel functional homologs of human DPP4 in several bacterial species inhabiting...
