Nat Phys
. 2024 Oct;
20(10):1670-1678.
PMID: 39416851
Filaments in the cell commonly treadmill. Driven by energy consumption, they grow on one end while shrinking on the other, causing filaments to appear motile even though individual proteins remain...

Nat Commun
. 2024 Jun;
15(1):5411.
PMID: 38926336
Most rod-shaped bacteria elongate by inserting new cell wall material into the inner surface of the cell sidewall. This is performed by class A penicillin binding proteins (PBPs) and a...

Nat Microbiol
. 2024 Mar;
9(4):1064-1074.
PMID: 38480901
Bacterial cell division requires septal peptidoglycan (sPG) synthesis by the divisome complex. Treadmilling of the essential tubulin homologue FtsZ has been implicated in septal constriction, though its precise role remains...

Whitley K, Middlemiss S, Jukes C, Dekker C, Holden S
Nat Protoc
. 2022 Feb;
17(3):847-869.
PMID: 35102310
Light microscopy is indispensable for analysis of bacterial spatial organization, yet the sizes and shapes of bacterial cells pose unique challenges to imaging. Bacterial cells are not much larger than...

Carney S, Ma W, Whitley K, Jia H, Lohman T, Luthey-Schulten Z, et al.
Nat Commun
. 2021 Dec;
12(1):7015.
PMID: 34853304
UvrD, a model for non-hexameric Superfamily 1 helicases, utilizes ATP hydrolysis to translocate stepwise along single-stranded DNA and unwind the duplex. Previous estimates of its step size have been indirect,...

Whitley K, Jukes C, Tregidgo N, Karinou E, Almada P, Cesbron Y, et al.
Nat Commun
. 2021 Apr;
12(1):2448.
PMID: 33907196
Despite the central role of division in bacterial physiology, how division proteins work together as a nanoscale machine to divide the cell remains poorly understood. Cell division by cell wall...

Makurath M, Whitley K, Nguyen B, Lohman T, Chemla Y
Nucleic Acids Res
. 2019 Jan;
47(5):2523-2532.
PMID: 30690484
Helicases are biomolecular motors that unwind nucleic acids, and their regulation is essential for proper maintenance of genomic integrity. Escherichia coli Rep helicase, whose primary role is to help restart...

PMID: 29664402
Helicases play key roles in genome maintenance, yet it remains elusive how these enzymes change conformations and how transitions between different conformational states regulate nucleic acid reshaping. Here, we developed...

Phys Rev Lett
. 2018 Feb;
120(6):068102.
PMID: 29481284
Despite their importance in biology and use in nanotechnology, the elastic behavior of nucleic acids on "ultrashort" (<15 nt) length scales remains poorly understood. Here, we use optical tweezers combined...
