What are Lysozymes?
Animals produce the antimicrobial enzyme lysozyme, which is a component of the innate immune system. This procedure is catalyzed by a glycoside hydrolase.
N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and N-acetyl-D-glucosamine residues in chitodextrins undergo ( beta 1 - 4)—linkage hydrolysis.
The majority of gram-positive bacteria's cell wall is made up of peptidoglycan.
The integrity of the bacterial cell walls is subsequently compromised by this hydrolysis, leading to lysis of the cells.
Saliva, human milk, mucus, and tears are all plentiful in lysozyme. Additionally, it can be found in the cytoplasmic granules of polymorphonuclear neutrophils and macrophages (PMNs). In egg white, lysozyme can be detected in large quantities. C-type lysozymes belong to the same glycoside hydrolase family 22 as -lactalbumin because of their similarity in sequence and structure. The LYZ gene in humans encodes the C-type lysozyme enzyme.
Classical pathway
The initial protein in the complement cascade, C1q, can start the classical pathway when it binds to the surface of the pathogen. As a result, it serves as a crucial link between the effector mechanisms of innate and adaptive immunity. It can also be triggered during an adaptive immune response by the binding of C1q to antibody:antigen complexes. The mannan-binding lectin, a serum protein, binds to mannose-containing carbohydrates on bacteria or viruses, starting the mannan-binding lectin route (MB-lectin pathway). The alternative pathway can also be started when a complement component that has become spontaneously activated attaches to a pathogen's surface. Each route produces a protease known as a C3 convertase through a series of processes.
