FIG. 2.
Schematic representation of the pathway leading to formation of a lipoprotein (see the text). LXGC (or LXAC) is the sequence known as a lipobox. UPLP, unmodified prolipoprotein; MPLP, modified prolipoprotein; ALP, apolipoprotein; LP, mature lipoprotein; Lgt, prolipoprotein diacylglyceryltransferase; SPII, lipoprotein-specific signal peptidase; Lnt, apolipoprotein N-acyl transferase; scissors, potential site of cleavage by SPII; -S-DAG, diacylglycerol in thioether linkage to cysteine; AcHN-, N-acylation of terminal amino group.
