FIG 2.

Human low-density lipoprotein (Hm LDL) particles are a source of exogenous fatty acids for synthesis of S. aureus phosphatidylglycerol. (A) Percentage of unsaturated phosphatidylglycerol (UPG) in comparison to the amount of total membrane PG of S. aureus grown in the presence (WT + Hm LDL) or absence (WT) of human LDLs. (B) Unsaturated fatty acid profile of membrane PG of S. aureus grown with (WT + Hm LDL) or without (WT) human LDLs plotted as a percentage of the amount of total PG fatty acids. UFA, MUFA, and PUFA, unsaturated, monounsaturated, and polyunsaturated fatty acids, respectively.
