In atomic biology, elastase is an agitator from the chic of proteases (peptidases) that breach down proteins.

Elastase break down elastin, an adaptable fibre that, calm with collagen, determines the automated backdrop of affiliation tissue. The neutrophil anatomy break down the Outer film protein A (OmpA) of E. coli and added Gram-negative bacteria. Elastase aswell has the important immunological role of breaking down Shigella acerbity factors. This is able through the break of peptide bonds in the ambition proteins. The specific peptide bonds broken are those on the carboxyl ancillary of small, berserk amino acids such as glycine, alanine, and valine. For added on how this is accomplished, see serine protease.
