The protein

Catalyzed reaction/ biological activity

inhibits [[protein|ParA]] dimerization and concomitant DNA-binding activity by stimulating [[protein|ParA]] ATPase activity [Pubmed|21235642]

recruits the condensin complex to the DNA origin region [Pubmed|24440393]

the dimer binds specifcally to the centromere-like ''parS'' sequence [Pubmed|25572315]

forms DNA bridging interactions around parS to condense DNA and earmark the bacterial chromosome for segregation [pubmed|29244022]

inhibits [[protein|ParA]] dimerization and concomitant DNA-binding activity by stimulating [[protein|ParA]] ATPase activity [Pubmed|21235642]

recruits the condensin complex to the DNA origin region [Pubmed|24440393]

the dimer binds specifcally to the centromere-like ''parS'' sequence [Pubmed|25572315]

prevents Z ring assembly over the bacterial nucleoid and helps fine tune the assembly of the Z ring at midcell during the cell cycle [pubmed|31152469]
