The min system prevents polar cell division in bacteria. Here, the biochemical characterization of the interaction of MinC and FtsZ from a Gram‐positive bacterium, Bacillus subtilis , is reported. B. subtilis MinC inhibits FtsZ polymerization in a pH‐dependent manner by preventing the formation of lateral associations between filaments. The inhibitory effect of MinC on FtsZ polymerization is counteracted by the presence of ZapA, a protein that promotes FtsZ filament bundling.
