Lysin a phage
Lysins, also known as endolysins or murein hydrolases, are hydrolytic enzymes produced by bacteriophages in order to cleave the host's cell wall during the final stage of the lytic cycle. Lysins are highly evolved enzymes that are able to target one of the five bonds in peptidoglycan (murein), the … Vedeți mai multe Double-stranded DNA phage lysins tend to lie within the 25 to 40 kDa range in terms of size. A notable exception is the streptococcal PlyC endolysin, which is 114 kDa. PlyC is not only the biggest and most potent lysin, … Vedeți mai multe Phage lysins are generally species or subspecies specific, which means that they are only effective against bacteria from which … Vedeți mai multe Phage lysins have been successfully tested in animal models to control pathogenic antibiotic-resistant bacteria found on Vedeți mai multe • Phage therapy • Enzybiotics • Lysozyme • OBPgp279 Vedeți mai multe It has been proposed that the main mechanism of evolution in phage lysins is the exchange of modular units, a process by which … Vedeți mai multe The lysin catalytic domain digests peptidoglycan locally at a high rate, which causes holes in the cell wall. Since the cross-linked peptidoglycan cell wall is the only … Vedeți mai multe One of the most problematic aspects of the use of phage lysins as antimicrobial agents is the potential immunogenicity of these enzymes.
