Function Catalyzes the phospholipid dependent N-acylation of the N-terminal cysteine of apolipoprotein, the last step in lipoprotein maturation.
Catalytic activity RHEA:48228: a glycerophospholipid + N-terminal S-1,2-diacyl-sn-glyceryl-L-cysteinyl-[lipoprotein] = a 2-acyl-sn-glycero-3-phospholipid + H(+) + N-acyl-S-1,2-diacyl-sn-glyceryl-L-cysteinyl-[lipoprotein]
Pathway Protein modification; lipoprotein biosynthesis (N-acyl transfer).
case not defined <Property:Membrane> or <Property:Membrane=1>
Subcellular location Cell membrane; Multi-pass membrane protein.
else case <Property:Membrane=2>
Subcellular location Cell inner membrane; Multi-pass membrane protein.
end case
Similarity Belongs to the CN hydrolase family. Apolipoprotein N-acyltransferase subfamily.
