Summary of "Extracellular transglycosylase and glyceraldehyde-3-phosphate dehydrogenase attributed to the anti-staphylococcal activity of Lactobacillus plantarum USM8613."

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-1β, 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.

Medical and Biotech [MESH] Definitions

An NAD-dependent glyceraldehyde-3-phosphate dehydrogenase found in the cytosol of eucaryotes. It catalyses the dehydrogenation and phosphorylation of GLYCERALDEHYDE 3-PHOSPHATE to 3-phospho-D-glyceroyl phosphate, which is an important step in the GLYCOLYSIS pathway.

An NADP-dependent, non-phosphorylating aldehyde dehydrogenase that catalyzes the irreversible oxidation of GLYCERALDEHYDE 3-PHOSPHATE to 3-phosphoglycerate. It is found in the cytosol of a wide variety of organisms.

Enzymes that catalyze the dehydrogenation of GLYCERALDEHYDE 3-PHOSPHATE. Several types of glyceraldehyde-3-phosphate-dehydrogenase exist including phosphorylating and non-phosphorylating varieties and ones that transfer hydrogen to NADP and ones that transfer hydrogen to NAD.

A phosphorylating glyceraldehyde-3-phosphate dehydrogenase found in the CHLOROPLASTS of higher plants. This enzyme exists as an A2B2 heterotetramer and transfers hydrogen to NADP. It plays an important role in catalyzing the reductive step of the Calvin cycle.

An enzyme that catalyzes the conversion of L-serine and 1-(indol-3-yl)glycerol 3-phosphate to L-tryptophan and glyceraldehyde 3-phosphate. It is a pyridoxal phosphate protein that also catalyzes the conversion of serine and indole into tryptophan and water and of indoleglycerol phosphate into indole and glyceraldehyde phosphate.
