Lipids associated with MelB_St. Lipids associated with purified MelB_St protein before and after a delipidation treatment were analyzed by HPLC/MS. a Molar contributions of lipids were calculated using response factors obtained from the analysis of known quantities of authentic lipid standards. For acyl-PG, the PG identical response factors were assumed because of lack of a standard for acy-PG. b Volcano plot. The statistics P value (log₁₀) is plotted against the fold-change (Log₂). Dot sizes for all species correspond to their relative contribution to the lipid pool associated with MelB_St protein. Red, PE; green, PG; black, CL
