Protein

Trypsin-1

Gene

PRSS1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Has activity against the synthetic substrates Boc-Phe-Ser-Arg-Mec, Boc-Leu-Thr-Arg-Mec, Boc-Gln-Ala-Arg-Mec and Boc-Val-Pro-Arg-Mec. The single-chain form is more active than the two-chain form against all of these substrates.1 Publication

Caution

Tyr-154 was proposed to be phosphorylated (PubMed:8683601) but it has been shown (PubMed:17087724) to be sulfated instead. Phosphate and sulfate groups are similar in mass and size, and this can lead to erroneous interpretation of the results.2 Publications

Catalytic activityi

Preferential cleavage: Arg-|-Xaa, Lys-|-Xaa.

Cofactori

Ca2+Note: Binds 1 Ca2+ ion per subunit.

Post-translational modificationi

Occurs in a single-chain form and a two-chain form, produced by proteolytic cleavage after Arg-122.
Sulfation at Tyr-154 increases selectivity towards basic versus apolar residues at the P2' position of inhibitors that bind in a substrate-like fashion. Although the increase in selectivity is relatively small, it may facilitate digestion of a broader range of dietary proteins.1 Publication
