Overview of variant regions encoding putative succinyl-CoA:3-oxo-acid CoA-transferase (SCOT) subunits in M. catarrhalis strains. Four variant regions were identified: type-1 regions contain two ORFs encoding the N-terminal part of the alpha subunit and the C-terminal part of the beta subunit; type-2 regions hold the same ORFs but one with an internal deletion and one in a truncated form; type-3 regions have two sets of overlapping ORFs encoding the N-terminal (501 nt) and C-terminal part (198 nt) of the alpha subunit and the N-terminal (249 nt) or the C-terminal part (363 nt) of the beta subunit, respectively; type-4 regions are identical to type-3 regions except that the ORF encoding the N-terminal part of the beta subunit is 273 nt in length.
