|Comment||This gene is found in type III secretion operons and has been shown to be essential for the invasion phenotype in Salmonella and a component of the secretion apparatus . The protein is known as OrgA in Salmonella due to its oxygen-dependent expression pattern in which low-oxygen levels up-regulate the gene . In Shigella the ghene is called MxiK and has been shown to be sessential for the proper assembly of the secretion needle complex .|
