TAS PROTEIN FROM ESCHERICHIA COLI IN COMPLEX WITH NADPH
Overview
BACKGROUND: The protein encoded by the gene ybgI was chosen as a target, for a structural genomics project emphasizing the relation of protein, structure to function. RESULTS: The structure of the ybgI protein is a, toroid composed of six polypeptide chains forming a trimer of dimers. Each, polypeptide chain binds two metal ions on the inside of the toroid., CONCLUSION: The toroidal structure is comparable to that of some proteins, that are involved in DNA metabolism. The di-nuclear metal site could imply, that the specific function of this protein is as a hydrolase-oxidase, enzyme.
