These included three operons containing genes that reached statistically significance on their own: U1306 ( nasD ) and U1096 and U1095 (both containing agrA and agrC ); and six additional operons containing CDS that did not reach statistical significance on their own: overlapping operons U605, U606 and U604, all containing the ileS gene; the U942 operon harbouring four riboflavin biosynthesis genes ( ribD , ribB , ribA and ribH ); the U254 operon containing genes involved in fatty acid metabolism ( vraA , vraB and vraC ); and the U331 operon which includes a single hypothetical protein ( SAOUHSC_00704 ) (Supplementary Data 2 ).
