similarity between the subunits of MukBEF and those of SMC-ScpAB is low, their overall molecular architecture observed by electron microscopy and phenotypic defects in mutants suggest that the two are functional homologs. As such, they are often collectively referred to as prokaryotic condensins.

MksBEF/Wadjet: More recently, a third type of bacterial SMC complex (called MksBEF), structurally similar to MukBEF, has been reported. ''Pseudomonas aeruginosa'' have both SMC-ScpAB
