New topoisomerase essential for chromosome segregation in E. coli
J Kato, Y Nishimura, R Imamura, H Niki, S Hiraga… - Cell, 1990 - cell.com
The nucleotide sequence of the parC gene essential for chromosome partition in E. coli was
determined. The deduced amino acid sequence was homologous to that of the A subunit of …

The trans‐envelope Tol–Pal complex is part of the cell division machinery and required for proper outer‐membrane invagination during cell constriction in E. coli
Fission of bacterial cells involves the co‐ordinated invagination of the envelope layers.
Invagination of the cytoplasmic membrane (IM) and peptidoglycan (PG) layer is likely driven by …

E. coli MukB protein involved in chromosome partition forms a homodimer with a rod‐and‐hinge structure having DNA binding and ATP/GTP binding activities.
H Niki, R Imamura, M Kitaoka, K Yamanaka… - The EMBO …, 1992 - embopress.org
mukB mutants of Escherichia coli are defective in the correct partitioning of replicated
chromosomes. This results in the appearance of normal‐sized anucleate (chromosome‐less) cells …
