In this recently published study, investigators in Chacabuco, Argentina conducted a study "To evaluate the role of the peptidase activities from sourdough lactic acid bacteria (LAB) in the degradation of alpha-gliadin fragments. Different proline-containing substrates were hydrolysed by LAB indicating pro-specific peptidase activities."
"Lactobacillus plantarum CRL 775 and Pediococcus pentosaceus CRL 792 displayed the highest tri- and di-peptidase activities, respectively. Lactobacillus plantarum strains hydrolysed more than 60%alpha-gliadin fragments corresponding to the 31-43 and 62-75 amino acids in the protein after 2 h. None of the LAB strains alone could ...
