Organism
Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage
Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK1164; minB
Summary
MinCD oscillates (migrates) between coating one half of the cell's membrane (minE ring to pole) to coating the other half every 40 secs, and this may help to identify the cell center. [More information is available at EcoGene: EG10596]. MinC acts to ensure correct placement of the septum during cell division by suppressing formation of septa at aberrant loci within the cell. [More information is available at EcoCyc: EG10596].
