THE STRUCTURE OF THE NITRATE/NITRITE RESPONSE REGULATOR PROTEIN NARL IN THE MONOCLINIC C2 CRYSTAL FORM
Overview
The structure of the Escherichia coli response regulator NarL has been, solved in a new, monoclinic space group, and compared with the earlier, orthorhombic crystal structure. Because the monoclinic crystal has two, independent NarL molecules per asymmetric unit, we now have three, completely independent snapshots of the NarL molecule: two from the, monoclinic form and one from the orthorhombic. Comparison of these three, structures shows the following: (a) The pairing of N and C domains of the, NarL molecule proposed from the earlier analysis is in fact correct, although the polypeptide chain connecting domains was, and remains, disordered and not completely visible. The new structure exhibits, identical relative orientation of N and C domains, and supplies some of, the missing residues, ... [(full description)]
