Purification, crystallization and preliminary X-ray characterization of Bacillus cereus arylamine N-­acetyltransferase 3 [(BACCR)NAT3]

B. cereus arylamine N-acetyltransferase 3 was expressed, purified and crystallized. X-ray diffraction data were collected to 2.42 Å resolution and the crystals belonged to the monoclinic space group C121.

Expression, purification and preliminary structural analysis of Escherichia coli MatP in complex with the matS DNA site

MatP is a small DNA-binding protein of about 18 kDa. In order to understand the DNA-compaction mechanism of MatP at an atomic level, the structures of apo MatP and of the nucleoprotein complex MatP-matS have been studied.
