PG - 700-6 LID - 10.1107/S1744309108018757 [doi] AB - The decameric inducible lysine decarboxylase (LdcI) from Escherichia coli has been crystallized in space groups C2 and C222(1); the Ta6Br12(2+) cluster was used to derivatize the C2 crystals. The method of single isomorphous replacement with anomalous scattering (SIRAS) as implemented in SHELXD was used to solve the Ta6Br12(2+)-derivatized structure to 5 A resolution. Many of the Ta6Br12(2+)-binding sites had twofold and fivefold noncrystallographic symmetry. Taking advantage of this feature, phase modification was performed in DM. The electron-density map of LdcI displays many features in agreement with the low-resolution negative-stain electron-density map [Snider et al. (2006), J. Biol. Chem. 281, 1532-1546].
