Thus, C-terminal swapped dimerization occurs and creates one intact active site in each LpxB mutant heterodimer.
Enzymatic activity assay showed that LpxB with mutations in the swapped portion of the dimer can be complemented by LpxB with mutation in the unswapped portion by forming an LpxB mutant heterodimer with more activity than individual LpxB mutants. Thus, C-terminal swapped dimerization occurs and creates one intact active site in each LpxB mutant heterodimer.
