L-aminoadipate-semialdehyde dehydrogenase-phosphopantetheinyl transferase (AASDHPPT) is an enzyme that in humans is encoded by the AASDHPPT gene.[5][6][7] It has been suggested that defects in the human gene result in pipecolic acidemia.[7]
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.[8] 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).[8] 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.[9]
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.
