Figure 5From: Use of nfsB, encoding nitroreductase, as a reporter gene to determine the mutational spectrum of spontaneous mutations in Neisseria gonorrhoeaeMutations in nfsB resulting in nitrofurantoin resistance. Missense mutations were identified at 9 different sites throughout the nfsB coding region. Residues affected by missense mutations are marked by *, and the altered amino acid is shown below.Back to article page
