ParB/RepB/Spo0J family partition protein, N-terminal domain
Spo0J (stage 0 sporulation protein J) is a ParB family member, a critical component of the ParABS-type bacterial chromosome segregation system. The Spo0J N-terminal region acts in protein-protein interaction and is adjacent to the DNA-binding domain that binds to parS sites. Two Spo0J bind per parS site, and Spo0J interacts with neighbors via the N-terminal domain to form oligomers via an Arginine-rich patch (RRXR). This superfamily represents the N-terminal domain of ParB, a DNA-binding component of the prokaryotic parABS partitioning system.
