In addition, another S. aureus antigen, rGapC, one of S. aureus’ surface proteins, possesses GAPDH activity and reversibly catalyzes the conversion of glyceraldehyde-3-phosphate into 1,3-bisphosphoglycerate by phosphorylation also increased survival rate when formulated with EPS30 in S. aureus-induced pneumonia (Figure S2C). This evidence concerns the gene GAPDH and susceptibility to pneumonia measurement.
