Hubs identified as potential targets from among the downregulated genes in Panchvalkal-exposed Pseudomonas aeruginosa

No.	Gene ID	Gene name	Functional role
1	PA0520	nirQ	Denitrification regulatory protein NirQ
2	PA0519	nirS	Heme d1 biosynthesis protein, which is important for denitrification (20)
3	PA0524	norB	Nitric oxide reductase subunit B
4	PA0523	norC	Nitric oxide reductase subunit C
5	PA0525	NorD	Nitric oxide reductase NorD protein
6	PA0521	NorE	Nitric oxide reductase NorE protein
7	PA3395	nosY	Nitrous oxide reductase; a Cu-processing system permease protein having role in denitrification pathway (21)
8	PA3396	nosL	A lipoprotein attached to the outer membrane described as a copper-binding protein. Regulator of nos operon, NosR also associates with NosL. This protein is probably responsible for the insertion and coordination of the multicopper center within NosZ (22).
