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, how many types of proteases are there?

six types

Also, where are proteases found? The body produces protease in the pancreas, but the pancreas doesn’t produce protease in a working condition. Instead, the protease produced in the pancreas has to be activated by another enzyme found in the intestine. Only after it is activated by the other enzyme, can the protease go to work breaking down protein.

how does serine protease work?

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.

How many amino acids are in protease?

Reprinted from https://en.wikipedia.org/wiki/Active_site. Usually, proteases possess a catalytic triad that refers to a group of three amino acid residues, such as Ser-His-Asp, Cys-His-Asp, Ser-His-His, Ser-Glu-Asp, and Ser-cisSer-Lys, functioning together at the center of the active site (Fig.
