Table 2.
The number of phosphates and charge of the LPS core polysaccharide structure are provided for several bacterial strain variants (first three rows) and model structures (remaining four rows). O-antigens were entirely absent in all rough model structures and only two O-antigens are included in the “smoother” structure. The PAH used in the simulations has a charge of +10 leading to the total charges listed in the final column. Negative and positive charges were neutralized in the simulations using the corresponding number of sodium cations or chloride anions, respectively.
Bacterial Strain | Number of Phosphate Units | Charge of LPS | Charge of LPS + PAH |
---|---|---|---|
S. oneidensis MR-1 | 5 | −7 | +3 |
S. oneidensis MR-4 variant 1 | 4 | −6 | +4 |
S. oneidensis MR-4 variant 2 | 6 | −5 | +5 |
Rough P. aeruginosa PAO1 variant | 6 | −12 | −2 |
“Smoother” P. aeruginosa PAO1 variant | 6 | −14 | −4 |
Rough S. typhimurium | 4 | −10 | 0 |
Rough E. coli | 5 | −9 | +1 |
