Angiotensin I-converting-enzyme-inhibitory and antimicrobial bioactive peptides

Bioactivities of peptides encrypted in major milk proteins are latent until they are released and activated by enzymatic proteolysis. After a brief description of the properties of some bioactive peptides, an overview of the angiotensin I-converting-enzyme (ACE)-inhibitory and antimicrobial peptides is given. Emphasis is on the capacity of lactic acid bacteria to generate ACE-inhibitory peptides and on the exploitation of the potential role of antimicrobial peptides derived from milk proteins
