Linearity of CcLpxI activity with time and protein concentration. Panel A. Fraction of 100 μM [β-32P]UDP-2,3-diacylglucosamine converted to the product lipid X at various times under standard assay conditions in the presence of 12.5 nM CcLpxI. Panel B. Fraction of 100 μM [β-32P]UDP-2,3-diacylglucosamine converted to lipid X per minute as a function of enzyme concentration. Panel C. An image of a silica TLC plate of an in vitro CcLpxI reaction run at an enzyme concentration of 40 nM.
