Vibrio anguillarum Fur mutants, 775met9 and 775met11, were characterized. V. anguillarum 775met9 had a change of D to G at position 104 located in the carboxy terminus resulting in impaired Fur activity. Computer analysis predicts perturbation of an alpha-helix in the carboxy terminus which may interfere with Fur protein conformation. Strain 775met11 had a change in the start codon resulting in no protein synthesis. The mutants are unstable, and reversion to the wild type occurs frequently.
