Gut microbiota enzyme

Gut microbiota enzymes comprise a broad range of proteins catalyzed by bacteria, archaea, fungi, and phages in the human gastrointestinal tract. These enzymes drive the digestion of otherwise non-digestible compounds, biotransformation of dietary and endogenous molecules, and generation of bioactive metabolites essential to host homeostasis and disease. Enzyme classes include glycoside hydrolases, polysaccharide lyases, bile salt hydrolases, amino acid decarboxylases, and others, which collectively mediate energy harvest, immune modulation, and cross-talk between host and microbiota. The diversity and abundance of these enzyme activities underpin the functional impact of the gut microbiota in health, disease, and drug response, making the collective enzymatic capacity of the gut microbiome an important, though complex, therapeutic target.
