Expression, purification, crystallization, and preliminary X-ray analysis of the N-terminal domain of Escherichia coli adenylyl transferase

Xu, Yibin; Wen, Daying; Clancy, Paula; Carr, Paul D; Ollis, David; Vasudevan, Subhash


A soluble N-terminal domain of the Escherichia coli adenylyl transferase (ATase) is responsible for deadenylylation activity of the intact enzyme. Previous studies of the deadenylylation activity have involved a fragment, AT-N423 (residues 1 to 423), which was extended by 17 amino acids to give AT-N440. This new domain is truncated at the end of a predicted helix and prior to a Q-linker. The domain was found to be very soluble and stable so that it could be purified to homogeneity and...[Show more]
