Lifting the concentration limit of mass photometry by PEG nanopattering

Lifting the concentration limit of mass photometry by PEG nanopattering

Kratochvil J, Asor R, Helmi S, Struwe WB, Kukura P

This paper by Jiri , Roi, Seham, Weston and Philipp demonstrates a substantial expansion in the application space of mass photometry through the combination of nanoparticle lithography with surface PEGylation, which results in a two orders of magnitude improvement in the upper concentration limit associated with mass photometry. Their artwork was chosen as cover art for NanoLetters 24 (33).

Myosin-5 varies its step length to carry cargo straight along the irregular F-actin track

Myosin-5 varies its step length to carry cargo straight along the irregular F-actin track

Fineberg A, Takagi Y, Thirumurugan K, Andrecka J, Billington N, Young G, Cole D, Burgess SA, Curd AP, Hammer JA, Sellers JR, Kukura P, Knight PJ

Myosin-5 carries cargoes inside cells by walking along helical F-actin filaments. Myosin-5 avoids walking helically by taking long steps equal to F-actin’s helical repeat. Previous measurements of step length show a broader spread of values than expected from the spatial resolution of the technique. We used iSCAT and electron microscopies, which have subnanometer precision, and find that the broad peak is really a family of narrow peaks that correspond to steps spanning different numbers of subunits along F-actin. We show that disorder within F-actin is the reason myosin-5 varies its step length because the F-actin subunit best oriented for walking in a straight line changes from step to step. Thus F-actin disorder has important impacts on cellular functions. This paper is the outcome of a longstanding collaboration between the Kukura group and NIH in Bethesda.

Single-molecule light scattering using optical holography

Single-molecule light scattering using optical holography

Thiele, JC, Pfitzner, E, Kukura, P

Scientists from our group have detected ultra-weak light scattering from single protein molecules using optical holography. Published in Nature Photonics, the new approach increases the sensitivity of the technique by five orders of magnitude compared to the current state of art. This breakthrough paves the way for a wider exploration of biomolecular interactions and applications in nanoscience.

A quantitative description for optical mass measurements of single biomolecules

A quantitative description for optical mass measurements of single biomolecules

Becker J, Peters J, Crooks I, Helmi S, Synakewicz M, Schuler B, Kukura P,

Jan's tour de force - where 9 years later we finally believe that the signals we see actually make sense, plus gives us lots of hope as to where MP can eventually go. And he answers probably the most often asked question after seminars: does shape matter? Well, a little bit...

Direct observation of the molecular mechanism underlying protein polymerization

Direct observation of the molecular mechanism underlying protein polymerization

Hundt N, Cole D, Hantke MF, Miller JJ, Struwe WB, Kukura P

One of the most challenging studies this group has ever completed. What started out as a simple idea required years of improvement in instrumentation, completely new approaches to data analysis and the development of a new model to understand how actin polymerises. We think a first in terms of demonstrating what can be done with MP in the context of highly heterogeneous mixtures.

Shape-Morphing of an Artificial Protein Cage with Unusual Geometry Induced by a Single Amino Acid Change

Shape-Morphing of an Artificial Protein Cage with Unusual Geometry Induced by a Single Amino Acid Change

Sharma M, Biela AP, Kowalczyk A, Borzęcka-Solarz K, Piette BMAG, Gaweł S, Bishop J, Kukura P, Benesch JLP, Imamura M, Scheuring S, and Heddle JG*

We have shown that a nano-sized spherical protein cage can undergo a major change in shape simply by changing a single amino acid. The work is interesting as it provides insight into how artificial protein containers can be engineered and molded into different shapes for different applications. It also is of interest from an evolutionary perspective: Typically, evolution is thought to occur gradually but this work is an example where major structural changes in large complexes come about from a single change.

Characterising biomolecular interactions and dynamics with mass photometry

Characterising biomolecular interactions and dynamics with mass photometry

Asor R, Kukura P

We review recent advances in our ability to characterise biomolecular structure, interactions and associated dynamics by mass photometry (MP), the label-free detection and mass measurement of individual biomolecules in solution. Molecular counting and identification provides direct access to relative abundance, and thereby affinities, while associated dynamics yield on- and off-rates. The molecular resolution afforded by MP enables these measurements as a function of stoichiometry and assembly at equilibrium, as opposed to the majority of existing solution-based methods. Together with future improvements in terms of assays and technological performance, MP is likely to provide mechanistic details of complex biomolecular processes.

Single molecule mass photometry reveals the dynamic oligomerization of human and plant peroxiredoxins

Single molecule mass photometry reveals the dynamic oligomerization of human and plant peroxiredoxins

Liebthal M, Kushwah MS, Kukura P, Dietz KJ

A collaboration that started on the blackboard after a talk in Bielefeld, involved a number of visits by Michael to Oxford and resulted in a great example how mass photometry can help with understanding polydispersity of proteins, and how that polydispersity relates to function.

Micromirror total internal reflection microscopy for high-performance single particle tracking at interfaces

Micromirror total internal reflection microscopy for high-performance single particle tracking at interfaces

Meng X, Sonn-Segev A, Schumacher A, Cole D, Young G, Thorpe S, Style RW, Dufresne ER, Kukura P.

It's not all about interferometric scattering. Darkfield, especially with super-optimised micromirrors is really, really awesome. If you are tracking metal nanoparticles, we think this is the way to go. And maybe even for molecules...

Mass photometry unchained from microscope cover glass. Detection, imaging, tracking and mass measurement of membrane-associated complexes. In our opinion, the beginning of a new era for MP.
