In all living organisms, it is essential to transmit genetic information faithfully to the next generation. The SMC-ParAB-parSsystem is widely employed for chromosome segregation in bacteria. A DNA-binding protein ParB nucleates onparSsites and must associate with neighboring DNA, a process known as spreading, to enable efficient chromosome segregation. Despite its importance, how the initial few ParB molecules nucleating atparSsites recruit hundreds of further ParB to spread is not fully understood. Here, we reconstitute aparS-dependent ParB spreading event using purified proteins fromCaulobacter crescentusand show that CTP is required for spreading. We further show that ParB spreading requires a closed DNA substrate, and a DNA-binding transcriptional regulator can act as a roadblock to attenuate spreading unidirectionally in vitro. Our biochemical reconstitutions recapitulate many observed in vivo properties of ParB and opens up avenues to investigate the interactions between ParB-parSwith ParA and SMC.
