CC   -!- FUNCTION: Part of a cell division machinery. May fulfill a coordination
CC       function between the Cdv proteins during cell division.
CC       {ECO:0000269|PubMed:24399085}.
CC   -!- DISRUPTION PHENOTYPE: Deletion mutant forms extremely small colonies on
CC       selective plates. Forms enlarged cells, with a highly elevated content
CC       of DNA. Mutant shows aberrant cellular localization of CdvA.
CC       {ECO:0000269|PubMed:24399085}.
