Figure 5From: A novel Geobacteraceae-specific outer membrane protein J (OmpJ) is essential for electron transport to Fe (III) and Mn (IV) oxides in Geobacter sulfurreducensHeme-stained protein composition of a WT (A) and an OmpJ-deficient mutant (B). A: Distribution of heme-stained proteins in subcellular fractions of G. sulfurreduces wild-type. Lane 1, total cell free extract; lane 2, soluble fractions; lane 3, inner membrane; and lane 4, outer membrane; 10 μg protein per lane. B: Distribution of heme-stained proteins in subcellular fractions of an OmpJ-deficient mutant. Lane 1, total cell free extract; lane 2, soluble fractions; lane 3, inner membrane; and lane 4, outer membrane; 10 μg protein per lane. Numbers at left are molecular masses in kDa.Back to article page
