SPI1 and Salmonella Infections: Similarly, a KEGG analysis revealed that yqiC is required for expressing virulence genes during Salmonella infection and the bacterial invasion of epithelial cells, including sipC and sipB (encoding translocons), fliC, fljB, sipA, sipC, sipD, sopD, sopE, and sptP (encoding SPI-1 effectors), spvB (encoding SPI-2 effectors), and nrfA (encoding NrfA for NO detoxification) (Additional file 12: Fig. S2, Additional file 13: Fig. S3).
