In molecular biology, elastase is an enzyme from the class of proteases (peptidases) that break down proteins. In particular, it is a serine protease.

Cells in APUD SystemNeuroscience
On:

Glomus cells are the cell type mainly located in the carotid bodies and aortic bodies. Glomus type I cells are peripheral chemoreceptors which sense the oxygen, carbon dioxide and pH levels of the blood. When there is a decrease in the blood’s pH, a decrease in oxygen (pO2), or an increase in carbon dioxide (pCO2), the carotid bodies andContinue Reading

Allysine–Allysine–Allysine–LysineCattleCrosslinks between four AAs
On:

Desmosine is an amino acid found uniquely in elastin, a protein found in connective tissue such as skin, lungs, and elastic arteries. Desmosine is a component of elastin and cross links with its isomer, isodesmosine, giving elasticity to the tissue. Detection of desmosine in urine, plasma or sputum samples can be a marker for elastin breakdown due to high elastaseContinue Reading
