L-aminoadipate-semialdehyde dehydrogenase-phosphopantetheinyl transferase (AASDHPPT) is an enzyme that in humans is encoded by the AASDHPPT gene. It has been suggested that defects in the human gene result in pipecolic acidemia.

The AASDHPPT protein catalyzes the post-translational modification phosphopantetheinylation, in which a 4'-phosphopantetheine (4'-PP) group derived from coenzyme A is covalently attached to target proteins in both cytosol and mitochondria. In the cytosol, these include fatty acid synthase (FASN), aminoadipate semialdehyde dehydrogenase (AASDH), and aldehyde dehydrogenase 1 family member L1 (ALDH1L1), whereas in mitochondria the targets are the mitochondrial acyl carrier protein (mtACP), aldehyde dehydrogenase 1 family member L2 (ALDH1L2), and dehydrogenase/reductase 2 (DHRS2). With the exception of DHRS2, the targets of AASDHPPT contain a acyl carrier protein (ACP) domain, a cofactor domain widespread across bacteria and eukaryotes with roles in the synthesis of fatty acids, polyketides, and nonribosomal peptides.

The protein encoded by this gene is similar to Saccharomyces cerevisiae LYS5, which is required for the activation of the alpha-aminoadipate dehydrogenase in the biosynthetic pathway of lysine. Yeast alpha-aminoadipate dehydrogenase converts alpha-biosynthetic-aminoadipate semialdehyde to alpha-aminoadipate.
