Abstract
Using 2D-NMR the four haems of Desulfovibrio vulgaris (Hildenborough) cytochromes, within the X-ray structure were fully cross-assigned according to their redox potential. The strategy used was based on a complete network of chemical exchange connectivities between the NMR signals obtained for all oxidation levels to the corresponding ones in the fully reduced spectrum [1992, Eur. J. Biochem., in press]. This unequivocal cross-assignment disagrees within earlier results obtained for the similar protein from Desulfovibrio vulgaris (Miyazaki F.) [1991, FEBS Lett. 285, 149–151]Keywords
