Proteases are enzymes that break down proteins by hydrolyzing peptide bonds. They play crucial roles in various biological processes, including infection and pathogenicity.
5 Must Know Facts For Your Next Test
Proteases are utilized by many pathogens to invade host tissues and evade immune responses.
In the oral cavity, proteases can degrade host proteins such as collagen and elastin, contributing to dental diseases like periodontitis.
Some eukaryotic pathogens secrete proteases as virulence factors to facilitate tissue invasion and nutrient acquisition.
Protease inhibitors are often used in therapeutic treatments to prevent microbial infections by blocking the activity of pathogen-derived proteases.
The activity of proteases is tightly regulated within organisms to prevent unnecessary tissue damage.
