RUBREDOXIN FROM DESULFOVIBRIO VULGARIS MIYAZAKI F, TRIGONAL CRYSTAL FORM
Overview
The structures of two crystal forms (form I, P3221, a = b = 43.7, c = 50.7, A; form II, P21, a = 27.3, b = 44.9, c = 51.2 A and beta = 90. 6 degrees ), of the rubredoxin from Desulfovibrio vulgaris Miyazaki F have been solved, by the molecular-replacement method. Form I has been refined at a, resolution of 2.0 A to an R value of 20.8% and includes 32 water, molecules. Form II includes 86 water molecules and has been refined at 1.9, A resolution to an R value of 17.5%. In form II, there are three molecules, in the asymmetric unit with the molecules related by a, non-crystallographic 32 symmetry axis. In both crystal forms, it was found, that only a few residues effectively participate in the formation of, intermolecular contacts along both the crystallographic (form I) and the, non-crystallographic (form II) 32 axes. The crystal structure of the form, II crystal is compared with those of other rubredoxin molecules from, anaerobic bacteria. From this comparison, a similarity in the core region, which is composed of aromatic residues and includes the active centre, has, been revealed.
