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

MA Gerding, Y Ogata, ND Pecora, H Niki… - Molecular …, 2007 - Wiley Online Library
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 …

Comparative functional genomics of the fission yeasts

…, N Friedman, JZ Dalgaard, P Baumann, H Niki… - Science, 2011 - science.org
The fission yeast clade—comprising Schizosaccharomyces pombe, S. octosporus, S. cryophilus,
and S. japonicus—occupies the basal branch of Ascomycete fungi and is an important …

Dynamic organization of chromosomal DNA in Escherichia coli

H Niki, Y Yamaichi, S Hiraga - Genes & Development, 2000 - genesdev.cshlp.org
We have revealed the subcellular localization of different DNA segments that are located at
∼230-kb intervals on theEscherichia coli chromosome using fluorescence in situ …

The new gene mukB codes for a 177 kd protein with coiled‐coil domains involved in chromosome partitioning of E. coli.

H Niki, A Jaffe, R Imamura, T Ogura, S Hiraga - The EMBO journal, 1991 - embopress.org
An Escherichia coli temperature sensitive mutant which produces spontaneously normal
size anucleate cells at low temperature was isolated. The mutant is defective in a previously …

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 …

Determination of bacterial rod shape by a novel cytoskeletal membrane protein

D Shiomi, M Sakai, H Niki - The EMBO journal, 2008 - embopress.org
Cell shape is critical for growth, and some genes are involved in bacterial cell morphogenesis.
Here, we report a novel gene, rodZ, required for the determination of rod shape in …

RNase E polypeptides lacking a carboxyl-terminal half suppress a mukB mutation in Escherichia coli

M Kido, K Yamanaka, T Mitani, H Niki… - Journal of …, 1996 - Am Soc Microbiol
We have isolated suppressor mutants that suppress temperature-sensitive colony formation
and anucleate cell production of a mukB mutation. A linkage group (smbB) of the suppressor …

[HTML][HTML] Subcellular distribution of actively partitioning F plasmid during the cell division cycle in E. coli

H Niki, S Hiraga - Cell, 1997 - cell.com
F plasmid is partitioned with fidelity to daughter cells during cell division cycle owing to two
trans-acting genes, sopA and sopB, and a cis-acting site, sopC. We visualized the subcellular …

Active segregation by the Bacillus subtilis partitioning system in Escherichia coli

Y Yamaichi, H Niki - … of the National Academy of Sciences, 2000 - National Acad Sciences
Bacterial genes required for proper partitioning consist of two transacting genes that encode
proteins and a cis-acting gene that functions like a centromere. Plasmids actively …
