Biology
In the case of the endolysin derived from the CAP 10-3 bacteriophage, its action specifically targets the degradation of the cell wall of Cutibacterium acnes, a Gram-positive bacterium with a cell wall rich in peptidoglycan, which is a crucial structural component. This endolysin is classified as an N-acetylmuramoyl-L-alanine amidase, which cleaves the bond between the N-acetylmuramic acid and the L-alanine residue in the peptidoglycan backbone.
By breaking down the peptidoglycan, the endolysin disrupts the rigid structure of the cell wall, leading to a loss of osmotic integrity. As a result, the bacterial cell can no longer withstand the internal pressure, causing rapid cell lysis. This mechanism is particularly effective against Gram-positive bacteria like C. acnes because they have a thick peptidoglycan layer that is more accessible to endolysins, unlike Gram-negative bacteria, which possess an additional outer membrane that restricts endolysin access.[1]
Advantages of Endolysins Against C. acnes:
- High Specificity: Endolysins are typically highly specific to their target bacteria, minimizing the risk of disrupting the beneficial skin microbiota.
- Low Risk of Resistance: Unlike traditional antibiotics, endolysins act on essential and conserved structural components of the bacterial cell wall, making it difficult for bacteria to develop resistance.
- Direct Bacterial Destruction: In contrast to other treatments that only inhibit bacterial growth, endolysins cause direct and rapid bacterial cell death, making them a potent tool for treating C. acnes-associated infections.
