In order to analyze the alanyl‐tRNA synthetase from the archaeon Archaeoglobus fulgidus , the N‐terminal fragment lacking the dimerization domain and the C‐terminal dimerization‐domain fragment were each overexpressed in Escherichia coli , purified and crystallized. A 3.7 Å resolution data set was collected for the N‐terminal fragment. The crystal belongs to the tetragonal space group P 4 1 or P 4 3 , with unit‐cell parameters a = b = 101.15, c = 124.24 Å. For the C‐terminal fragment, a SeMet MAD data set was collected to 3.2 Å resolution. The crystal belongs to the orthorhombic space group P 222 1 , with unit‐cell parameters a = 124.15, b = 131.91, c = 138.68 Å.
