CC -!- FUNCTION: Catalyzes the phospholipid dependent N-acylation of the N-
CC terminal cysteine of apolipoprotein, the last step in lipoprotein
CC maturation. {ECO:0000255|HAMAP-Rule:MF_01148}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a glycerophospholipid + N-terminal S-1,2-diacyl-sn-glyceryl-L-
CC cysteinyl-[lipoprotein] = a 2-acyl-sn-glycero-3-phospholipid + H(+) +
CC N-acyl-S-1,2-diacyl-sn-glyceryl-L-cysteinyl-[lipoprotein];
CC Xref=Rhea:RHEA:48228, Rhea:RHEA-COMP:14681, Rhea:RHEA-COMP:14684,

CC ChEBI:CHEBI:140657, ChEBI:CHEBI:140660; EC=2.3.1.269;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01148};
CC -!- PATHWAY: Protein modification; lipoprotein biosynthesis (N-acyl
CC transfer). {ECO:0000255|HAMAP-Rule:MF_01148}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01148}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01148}.
CC -!- SIMILARITY: Belongs to the CN hydrolase family. Apolipoprotein N-
CC acyltransferase subfamily. {ECO:0000255|HAMAP-Rule:MF_01148}.
