Abstract:Bacteria exploit specialized secretion systems to assist in competition for resources, in collaboration and in communication. Here, a protocol for the recombinant production, purification and crystallization of a protein linked to the Acinetobacter baumannii type VI secretion system is provided. A high-resolution structure of this trimeric protein is reported, revealing the characteristic dual β–α–β subunit fold typical of longer subunit members of the tautomerase superfamily. The protein does not appear to be… Show more
