The McdB protein was shown via two hybrid studies to interact with carboxysome shell proteins.
The two less abundant plasmid partition systems employ actin and tubulin-like NTPases. Initial data suggested that Walker-box ParA proteins also form polymers for segregation However, recent studies including in vitro reconstitution experiments, super resolution analyses and crystallographic analyses support a non-polymer, diffusion-ratchet like mechanism 21— The basis for this trigger was revealed by biochemical and structural studies, which showed that ParA proteins are monomeric in their apo forms and dimerize in the presence of ATP 32— ParA dimerization is mediated by so-called signature lysine residues present in the Walker A motifs of these proteins, which forms inter-monomer contacts to the ATP bound at the other subunit of the dimer They do so by binding with high specificity and cooperativity to DNA centromeres, which consist of repeat elements.
These are 16 base pair bp elements in many well-studied chromosomal centromeres and consist of repeat elements of sometimes varying length and sequence in plasmid centromeres 34— For example, the P1 plasmid centromere consists of heptamer and hexamer boxes 36 , Binding of ParB proteins to centromeres leads to the formation of a higher order structure called the partition complex Indeed, studies by the Bouet and Dillingham labs revealed that chromosomal ParB proteins form complex, bridged 3D structures, with the C-terminal domains mediating bridging and DNA condensation 43 , Structures and biochemical analyses indicate that ParB proteins bind at the dimer interface, between ParA subunits, and employ arginine residue s that appear to aid in ParA ATP hydrolysis 32 , 33 , Repeated cycles of ParA binding and release from the nucleoid with concomitant capture of the ParB-DNA cargo somehow leads to equidistribution of the cargo.
One hypothesis is that the ParA proteins equilibrate to DNA dense regions that form at the two poles of the dividing nucleoids, allowing for each daughter cell to retain a cargo DNA via a piggy back mechanism The carboxysome retention machinery appears similar to Walker-box DNA segregation systems In particular, the McdA protein, which like partition ParA proteins has a putative Walker-box fold, appears to bind the nucleoid DNA in the presence of ATP and data suggests it also uses the nucleoid as a track to move its molecular cargo, in this case, carboxysomes Indeed, a hallmark feature of a large group of ATPases, which includes not only partition ParAs but proteins involved in nitrogen fixation and spatial regulation of cell division, is the presence of two lysines within the phosphate binding P-loop of the Walker A motif.
