Armitage J
Microbiology (Reading)
. 2024 Feb;
170(2).
PMID: 38363121
Fifty years of research has transformed our understanding of bacterial movement from one of description, based on a limited number of electron micrographs and some low-magnification studies of cells moving...

PMID: 38226962
Bacteria swim using membrane-spanning, electrochemical gradient-powered motors that rotate semi-rigid helical filaments. This primer provides a brief overview of the basic synthesis, structure and operation of these nanomachines. Details and...

PMID: 35722353
has 2 flagellar operons, one, Fla2, encoding a polar tuft that is not expressed under laboratory conditions and a second, Fla1, encoding a single randomly positioned flagellum. This single flagellum,...

mBio
. 2022 Jan;
13(1):e0367221.
PMID: 35073746
The bacterial cytoplasm is a very crowded environment, and changes in crowding are thought to have an impact on cellular processes including protein folding, molecular diffusion and complex formation. Previous...

Armitage J, Berry R
Annu Rev Microbiol
. 2020 Jul;
74:181-200.
PMID: 32603624
The bacterial flagellar motor is the most complex structure in the bacterial cell, driving the ion-driven rotation of the helical flagellum. The ordered expression of the regulon and the assembly...

Int J Mol Sci
. 2019 Oct;
20(20).
PMID: 31615130
has two chemotaxis clusters, an -like cluster with membrane-spanning chemoreceptors and a less-understood cytoplasmic cluster. The cytoplasmic CheA is split into CheA, a kinase, and CheA, a His-domain phosphorylated by...

Baker A, Webster S, Diepold A, Kuchma S, Bordeleau E, Armitage J, et al.
J Bacteriol
. 2019 Jan;
201(18).
PMID: 30642992
Flagellar motility is critical for surface attachment and biofilm formation in many bacteria. A key regulator of flagellar motility in and other microbes is cyclic diguanylate (c-di-GMP). High levels of...

mBio
. 2019 Jan;
10(1).
PMID: 30602584
Coordinating chromosome duplication and segregation with cell division is clearly critical for bacterial species with one chromosome. The precise choreography required is even more complex in species with more than...

Delalez N, Armitage J
Methods Mol Biol
. 2018 Jul;
1805:33-49.
PMID: 29971711
The bacterial flagellar motor is one of the few rotary motors in nature. Only ∼50 nm in diameter, this transmembrane, ion-driven nanomachine rotates a semirigid helical flagellum at speeds of...

FEMS Microbiol Rev
. 2018 Jun;
42(4):462-476.
PMID: 29945173
The bacterial cytoplasm is not a homogeneous solution of macromolecules, but rather a highly organized and compartmentalized space where the clustering and segregation of macromolecular complexes in certain cell regions...
