What does serine protease do?

Serine proteases (or serine endopeptidases) are enzymes that cleave peptide bonds in proteins, in which serine serves as the nucleophilic amino acid at the (enzyme's) active site. They are found ubiquitously in both eukaryotes and prokaryotes.

In respect to this, what does protease do in the body?

The Role of Protease Yes, protease helps break down protein in food into amino acids, which the body can then use for energy, but where proteases stand apart is the fact that they also play a number of other roles in essential processes, such as: Blood clotting.

Subsequently, question is, how many serine proteases are there? Of 699 proteases in man, 178 are serine proteases and 138 of them belong to the S1 protease family.

In this way, is trypsin a serine protease?

Trypsin (EC 3.4.21.4) is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyzes proteins. Trypsin is formed in the small intestine when its proenzyme form, the trypsinogen produced by the pancreas, is activated.

How do Serine Protease inhibitors work?

Serine protease inhibitors. Serine protease inhibitors, or serpins, comprise a family of proteins that antagonize the activity of serine proteases. In this mechanism, the serpin presents a substrate-mimicking peptide sequence—the reactive center loop—to its target serine protease.
