Cloning, purification and preliminary crystallographic analysis of the Bacillus subtilis GTPase YphC–GDP complex
Crystals of a selenomethionine-incorporated YphC–GDP complex have been grown using the hanging-drop vapour-diffusion method and polyethylene glycol as a precipitating agent. The Bacillus subtilis YphC gene encodes an essential GTPase thought to be involved in ribosome binding and whose protein product may represent a target for the development of a novel antibacterial agent. Sequence analysis reveals that YphC belongs to the EngA family of GTPases, which uniquely contain two adjacent GTP-binding domains. Crystals of a selenomethionine-incorporated YphC–GDP complex have been grown using the hanging-drop vapour-diffusion method and polyethylene glycol as a precipitating agent. The crystals belong to space group P2{sub 1}2{sub 1}2{sub 1}, with unit-cell parameters a = 62.71, b = 65.05, c = 110.61 Å, and have one molecule in the asymmetric unit. Data sets at three different wavelengths were collected on a single crystal to 2.5 Å resolution at the Daresbury SRS in order to solve the structure by MAD. Ultimately, analysis of YphC in complex with GDP may allow a greater understanding of the EngA family of essential GTPases.
