FIG. 5.

Structures of LacK′-′MalK chimeras. MalK- and LacK-derived sequences of the chimeras are represented by open and shaded bars, respectively. At the joining points, the last amino acid residue originating from LacK and the first amino acid residue derived from MalK are shown above and below the bars, respectively. MalK is shown with the assignment of putative functional domains (see also the legend to Fig. 1).
