Increasing levels of antibiotic resistance in pathogens, including Staphylococcus aureus, remains a serious problem for public health, leading to the need for better alternative antimicrobial strategies. The antimicrobial proteins produced by Lactobacillus plantarum USM8613 attributed to its anti-staphylococcal activity were identified as extracellular transglycosylase and glyceraldehyde-3-phosphate dehydrogenase (GADPH), both with different mechanisms of action. Extracellular transglycosylase, which contains a LysM domain, exerts a cell wall-mediated killing mechanism, while GADPH penetrates into S. aureus cells and subsequently induces the overexpression of autolysis regulators, resulting in S. aureus autolysis. Both extracellular transglycosylase and GADPH exert anti-inflammatory effects in S. aureus-infected HaCaT cells by reducing the expression and production of TLR-2, hBDs and various pro-inflammatory cytokines (IL-1α, IL-1ß, IL-6, TNF-α, and IL-8). Taken together, extracellular transglycosylase and GADPH produced by L. plantarum USM8613 could potentially be applied as an alternative therapeutic agent to treat S. aureus skin infections and promote skin health.
