The protein

Catalyzed reaction/ biological activity

• aids in moving DNA away from the closing septum, binds DNA, DNA-dependent ATPase activity [Pubmed|19818024]
• the two DNA translocases [protein|DF77B46666595E86081C5345C91E08F86DF9FAEE|SftA] and [protein|125325B485FBC60798EDA4B4BFB24C6FCBC4C513|SpoIIIE] synergistically affect chromosome dimer resolution presumably by positioning the dif sites in close proximity, before or after completion of cell division, respectively [Pubmed|21239579]
