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

• Protein family: MinD subfamily (according to Swiss-Prot)
