1.  Overexpression, purification, crystallization and preliminary X-ray cystallographic studies of a proline-specific aminopeptidase from Aneurinibacillus sp. strain AM-1 
Preliminary X-ray crystallographic study of a proline-specific aminopepitdase from Aneurinibacillus sp, strain AM-1 was carried out.
To elucidate the structure and molecular mechanism of a characteristic proline-specific aminopeptidase produced by the thermophile Aneurinibacillus sp. strain AM-1, its gene was cloned and the recombinant protein was overexpressed in Escherichia coli, purified and crystallized using the hanging-drop vapour-diffusion method. X-ray diffraction data were collected to 1.8 Å resolution from the recombinant aminopeptidase crystal. The crystals belong to the orthorhombic space group P21212, with unit-cell parameters a = 93.62, b = 68.20, c = 76.84 Å. A complete data set was also obtained from crystals of SeMet-substituted aminopeptidase. Data in the resolution range 20–2.1 Å from the MAD data set from the SeMet-substituted crystal were used for phase determination.
