Figure 1From: Diverse allosteric and catalytic functions of tetrameric d-lactate dehydrogenases from three Gram-negative bacteriaSDS-PAGE and size-exclusion chromatography of the purified enzymes. a) Lane 1, molecular mass standards (kDa); lane 2, FNLDH; lane 3, PALDH; lane 4, ECLDH. b) Elution of the enzymes from Superdex 200 with the buffers described in `Materials and methods'. Solid, dashed, and dotted lines indicate FNLDH, PALDH, and ECLDH, respectively.Back to article page
