Protein

Nucleoid occlusion factor SlmA

Gene

ttk

Organism
Escherichia coli (strain UTI89 / UPEC)
Status
Unreviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Required for nucleoid occlusion (NO) phenomenon, which prevents Z-ring formation and cell division over the nucleoid. Acts as a DNA-associated cell division inhibitor that binds simultaneously chromosomal DNA and FtsZ, and disrupts the assembly of FtsZ polymers. SlmA-DNA-binding sequences (SBS) are dispersed on non-Ter regions of the chromosome, preventing FtsZ polymerization at these regions.UniRule annotationSAAS annotation
