The Ogden syndrome NAA10 p.Ser37Pro (S37P) mutant shows reduced in vitro catalytic activity and reduced subunit complexation with NAA15 in immunoprecipitation experiments. In a yeast complementation model, wild-type human NatA fully rescued NatA-deletion yeast phenotypes whereas the S37P mutant only partially rescued, and quantitative Nt-acetylome analysis showed globally reduced N-terminal acetylation of NatA substrates in yeast expressing the mutant compared to wild-type hNatA. |

Monomeric recombinant hARD1/NAA10 exhibits lysine acetyltransferase (KAT) activity in vitro, but this activity is lost as the protein forms oligomers over time; size-exclusion analysis showed oligomeric NAA10 lacks KAT activity while the monomeric form retains it, with activity dependent on reactant concentrations and reaction time. |
