2.3.1.255 hanging drop vapor diffusion method, using 0.1 M sodium acetate pH 4.6, 8% (w/v) polyethylene glycol 4000 and 35% (v/v) glycerol 2.3.1.255 hanging drop vapor diffusion method, using 0.1 M trisodium citrate pH 5.6, 20% (v/v) 2-propanol, 20% (w/v) polyethylene glycol 4000 and 0.2 M sodium chloride 2.3.1.255 holo-NatA complex in the absence and presence of a bisubstrate peptide-CoA-conjugate inhibitor, as well as the uncomplexed Naa10p catalytic subunit, X-ray diffraction structure determination and analysis 2.3.1.255 in complex with CoA and with CoA/peptide, sitting drop vapor diffusion method, using 30% (w/v) PEG 4,000, 0.1 M sodium acetate trihydrate, pH 4.6, and 0.2 M (NH4)2SO4 or 5% (w/v) PEG 4,000, 0.1 M sodium acetate trihydrate pH 4.2, and 0.1 M (NH4)2SO4 2.3.1.255 structure of the 100 kDa holo-NatA complex in the absence and presence of a bisubstrate peptide-CoA conjugate inhibitor, and structure of the uncomplexed Naa10p catalytic subunit. The NatA-Naa15p auxiliary subunit contains 13 TPR motifs and adopts a ring-like topology that wraps around the NatA-Naa10p subunit, an interaction that alters the Naa10p active site for substrate-specific acetylation
