In vitro N-terminal acetyltransferase activity of Naa10 variants. Purified recombinant hNaa10 WT and mutants were mixed with 300 mM oligopeptide and 600 mM acetyl-CoA and incubated at 37 °C. (a) Time-dependent acetylation of the oligopeptide EEEI by purified recombinant hNaa10 WT, hNaa10 p.(Arg116Trp), hNaa10 p.(Val107Phe) and hNaa10 p.(Ser37Pro). The reaction was stopped at different time points by the addition of 10% TFA. (b) NAT activity of hNaa10 WT and hNaa10 mutants towards substrate oligopeptides EEEI, DDDI and SESS. Bars are showing product formation in (or close to) the linear phase of the reaction, after 10 min of incubation. Measurements statistically significant from hNaa10 WT by independent two-tailed t-tests are indicated with an asterisk (P<0.05).
