Disease relevance of slmA

In rod-shaped bacteria such as Escherichia coli and Bacillus subtilis, two factors involved in this regulation are the Min system and nucleoid occlusion [1].

High impact information on slmA

Nucleoid occlusion is a poorly understood mechanism whereby the nucleoid prevents division in the cylindrical part of the cell, until chromosome segregation has occurred near midcell [2].
Evidence for polar positional information independent of cell division and nucleoid occlusion [3].
Nucleoid occlusion prevents division over the nucleoids and directs it by default to the mid-cell region between segregating nucleoids or to polar regions while the Min system prevents division in polar regions [4].
