Fig. 3From: Effect of site-directed mutagenesis at the GGEEF domain of the biofilm forming GGEEF protein from Vibrio cholerae Assay for motility. Triphenyl tetrazolium chloride (TTC) forms a red colored compound, formazan, when absorbed into a bacterial cell. While Sebox3 shows almost no motility, Sebox5, 6 and 7 show migration from the initial stab lineBack to article page
