hanging drop vapor diffusion method, using 0.2 M calcium acetate, 0.1 M sodium cacodylate and 18% (w/v) PEG 8000 pH 6.2 for the native protein or 18% (w/v) PEG 8000, 0.2 M calcium acetate and 0.1 M sodium acetate pH 5.8 for the SeMet-substituted protein
crystal structure of AmiF is solved to 1.75 A resolution using single-wavelength anomalous dispersion methods. The structure consists of a homohexamer related by 3fold symmetry in which each subunit has an alpha-beta-beta-alpha four-layer architecture characteristic of the nitrilase superfamily
after incubation at the optimal temperature for activity of the enzyme (50°C) for 40 h, the enzyme maintains around 95% of its initial activity. Activity is gradually lost when the enzyme is incubated at temperatures over 65°C for 30 min. The melting temperature is at 73.5°C
