Erotisk Min System - Wikipedia Pictures
Min Fru component participates in generating a dynamic oscillation of FtsZ protein inhibition between the two bacterial poles to precisely specify the mid-zone of the cell, allowing the cell to accurately divide in two. This system is known to function in conjunction with a second negative regulatory system, the nucleoid occlusion system NOto ensure proper spatial and temporal Warqaad Tube Com of chromosomal segregation and division.
The initial discovery of this family of proteins is attributed to Adler et al. First identified as E. This caused miniature vesicles to pinch off, void of Min Fru molecular constituents permitting it to exist as a viable bacterial cell. Minicells are achromosomal cells that are products of aberrant cell division, and contain RNA and protein, but little or no Min Fru DNA. This finding led to the identification of three interacting proteins involved in a dynamic system of localizing the mid-zone of the cell for properly controlled cell division.
The Min Min Fru prevent the FtsZ ring from being placed anywhere but near the mid cell and are hypothesized to be involved in a spatial regulatory mechanism that links size increases prior to cell division to FtsZ polymerization in the middle of the cell. One model of Z-ring formation permits its formation only after a certain spatial signal that tells the cell that it is big enough to divide.
MinD is only able to bind to the membrane when in its Min Fru conformation. Once anchored, the protein polymerizes, resulting in clusters of MinD. These clusters bind and then activate another protein called MinCwhich has activity only when bound by MinD. The high concentration of a FtsZ polymerization inhibitor at the poles prevents FtsZ from initiating division at anywhere Min Fru the mid-cell.
MinE is involved in preventing the formation of MinCD complexes in the middle of the cell. Min Fru forms a ring near each cell pole.
This ring is not like the Z-ring. This prevents MinC Kindi Stone deactivating FtsZ. As a consequence, this activity imparts regional specificity to Min localization.
Mutations that prevent the formation of MinE rings result in the MinCD zone extending well beyond the polar zones, preventing FtsZ to polymerize and to perform cell division. In vivo observations show that the oscillation of Min proteins between cell poles occurs approximately every 50 seconds.
Bacillus subtilis has been shown to have static concentrations of MinC and MinD at the cell poles. Min Fru dynamic behavior of Min proteins has been reconstituted in vitro using artificial lipid bilayers,  with varying lipid composition  and different confinement geometry  Min Fru mimics for the cell membrane.
Additional study is required to elucidate the extent of temporal and spatial signaling permissible by this biological function. These in vitro systems offered unprecedented access to features such as residence times and molecular motility.
