Identification of complex of Paraprevotella clara 00502 protein and human PRSS2


ABSTRACT: 00502 protein derived from Paraprevotella clara, as well as mixture of 00502 protein and human PRSS2 were analyzed by Native-PAGE. The observed bands were cut out and digested in-gel. The digested peptides were analyzed by DDA-MS using Q Exactive HF-X .

Increased levels of proteases, such as trypsin, in the distal intestine have been implicated in intestinal pathological conditions<sup>1-3</sup>. However, the players and mechanisms that underlie protease regulation in the intestinal lumen have remained unclear. Here we show that Paraprevotella strains isolated from the faecal microbiome of healthy human donors are potent trypsin-degrading commensals. Mechanistically, Paraprevotella recruit trypsin to the bacterial surface through type IX secret  ...[more]
