MinC

• Description: cell-division inhibitor (septum placement), destabilizes FtsZ-rings at new cell poles, part of the Min system (with DivIVA, MinD, MinJ), Noc and the Min system ensure the efficient utilization of the division site at midcell in by ensuring Z ring placement

The protein

Basic information/ Evolution

• Catalyzed reaction/ biological activity:
  • The Min system prevents minicell formation adjacent to recently completed division sites by promoting the disassembly of the cytokinetic ring, thereby ensuring that cell division occurs only once per cell cycle PubMed
  • binds the C-terminal domain of FtsZ to inhibit its polymerization PubMed

• Protein family: minC family (according to Swiss-Prot)
