The tfeB gene encoding TFEβ is non-essential in H. volcanii. (A) Southern blot of EcoRV digest confirming deletion of tfeB in H2644 and H2645. (B) Deletion of tfeB confers a slow-growth phenotype in H2644 and H2645, versus the parent strain H53. Data from the mean of four repeats (and standard error) is plotted on a log2 scale, the generation time in exponential phase is shown in bold (exponential growth phase is indicated by straight-line fit between perpendicular marks, R2 = 0.99 for all strains). (C) The growth defect conferred by deletion of tfeB in H2644 is complemented by in trans expression of tfeB (eV, empty vector).
