Numbat: an interactive software tool for fitting Δχ-tensors to molecular coordinates using pseudocontact shifts

Abstract:

Pseudocontact shift (PCS) effects induced by a paramagnetic lanthanide bound to a protein have become increasingly popular in NMR spectroscopy as they yield a complementary set of orientational and long-range structural restraints. PCS are a manifestation of the χ-tensor anisotropy, the Δχ-tensor, which in turn can be determined from the PCS. Once the Δχ-tensor has been determined, PCS become powerful long-range restraints for the study of protein structure and protein–ligand complexes. Here we present the newly developed package Numbat (New User-friendly Method Built for Automatic Δχ-Tensor determination). With a Graphical User Interface (GUI) that allows a high degree of interactivity, Numbat is specifically designed for the computation of the complete set of Δχ-tensor parameters (including shape, location and orientation with respect to the protein) from a set of experimentally measured PCS and the protein structure coordinates. Use of the program for Linux and Windows operating systems is illustrated by building a model of the complex between the E. coli DNA polymerase III subunits ε186 and θ using PCS.

We demonstrate the efficiency of the method on a synthetic, yet realistic case based on the lanthanide-labeled N-terminal Îµ domain of the E. coli DNA polymerase III (Îµ186) in complex with the HOT domain.
