Table 2 Effect of ATP, EnvZ, OmpR and volume at high and low osmolarity conditions. The levels of low and high ATP taken were 3 mM and 5 mM respectively. The volume taken was 10% and 20% decrease with respect to 10-15. At low EnvZ, the level was taken as nil and was elevated till 10 fold (1000 molecules with respect to 102 reported value). Similarly for OmpR a 10 fold increase and decrease from the reported value of 2100 was taken (20000 and 200 molecules respectively)
