  • PubMed Abstract: 
  • The NMR solution structure of the oxidized HiPIP from Chromatium vinosum has been solved. Despite the fact that the protein is paramagnetic, 85% of the 1H and 80% of the 15N signals have been assigned. Through 1537 NOEs, out of which 1142 were found to be relevant for the structure determination, a family of structures has been obtained by distance geometry calculations ...

    The NMR solution structure of the oxidized HiPIP from Chromatium vinosum has been solved. Despite the fact that the protein is paramagnetic, 85% of the 1H and 80% of the 15N signals have been assigned. Through 1537 NOEs, out of which 1142 were found to be relevant for the structure determination, a family of structures has been obtained by distance geometry calculations. These structures have then been subjected to restrained energy minimization (REM) and restrained molecular dynamics (RMD) calculations in vacuum. Finally, the mean structure of the RMD family has been treated through RMD in water. The RMSD values for the backbone and heavy atoms within the RMD family are 0.57 +/- 0.14 and 1.08 +/- 0.16 A, respectively. These values together with other parameters indicate that the structure is of good quality and as good as the structure of the reduced protein. The RMDw structures of the reduced and oxidized proteins are different beyond the experimental indetermination. The set of constraints for the reduced and oxidized forms have been used to treat the available X-ray structure by RMD in water. The two structures generated in this way are quite similar to their respective solution structures, thus confirming that the experimental constraints are capable of yielding two different structures from the same starting structural model. This is the first time that independently determined solution structures of two redox states of a paramagnetic protein are available. Differences between them and the X-ray structure are discussed.
