Revision of the haem-core architecture in the tetraheam cytochrome c3 from Desulfovib

Revision of the haem-core architecture in the tetraheam cytochrome c3 from Desulfovibrio baculatus by two-dimensional 1H NMR.

Authors: Coutinho IB, Turner DL, Legall J, Xavier AV

The haem-core architecture in cytochrome c3 isolated from Desulfovibrio baculatus (Norway 4) was probed using two-dimensional 1H NMR. Interhaem connectivities detected in NOE spectroscopy experiments performed at short mixing times are incompatible with the structure of the protein determined by X-ray crystallography, but agree instead with the haem arrangement found in cytochrome c3 from Desulfovibrio vulgaris (Miyazaki). These experiments show unequivocally that the relative orientation of the four haems in the two proteins is the same and does not involve the 180 degrees rotation of haems I and IV indicated in the X-ray structure determined for the cytochrome c3 from D. baculatus (Norway 4).

Installation of GROMACS 3.3.1 on Dell Inspiron 6400 with Fedora Core 6, Test 3, Dual Core processor This is not really a "hard-core NMR topic" but it could be useful for people who try to complement dynamics data from NMR relaxation experiments with MD simulations. I had really hard time trying to install the newer versions of Gromacs 3.3 and 3.3.1 on my laptop (Dell Inspiron 6400 Dual Core processor) . The laptop used to run Suse 10.1 that was recently replaced with Fedora Core 6 Test 3 (that finally supports Intel integrated mobile 945 video cards). With both OS, Gromacs 3.3.x could be installed, however, its sub-program "genion" failed (the program never ends while consuming 100%...	administrator	Molecular Dynamics programs	0	10-04-2006 11:50 AM
