Technique - (3) Native mass spectrometry of protein complexes

Type: Experimental

Description:

Department(s)/lab(s): Biological Engineering | Bathe Lab (Laboratory for Nucleic Acid Nanotechnology) @ MIT
Summary:

PREFERRED. Bathe's lab programs DNA and RNA into custom 2D/3D nanoscale materials (DNA origami via the DAEDALUS algorithm) for applications spanning vaccines/therapeutics, massive molecular data storage, and — most relevant here — using DNA as a programmable scaffold to organize photonic and quantum-optical elements (mimicking quantum coherence effects seen in photosynthetic light-harvesting) and single-molecule optical biosensing.

Department(s)/lab(s): Chemistry (Physical and Theoretical Chemistry Laboratory) | Benesch Group @ Oxford
Summary:

Benesch combines native mass spectrometry with mass photometry (developed jointly with Philipp Kukura) and other biophysical methods to determine how proteins, including molecular chaperones, assemble, interact and evolve, integrating single-molecule bioanalytical technologies for proteomics.

Department(s)/lab(s): School of Physics | Curmi Molecular Biophysics Laboratory @ UNSW
Summary:

Curmi is a structural and single-molecule biophysicist whose most-cited work is on the light-harvesting antenna proteins of cryptophyte algae, where he and collaborators reported long-lived electronic coherence at ambient temperature — one of the founding results of the quantum-biology field and still one of its most argued-over. His group determines the structures of these antenna complexes and engineers them, and separately works on protein-based molecular motors and on single-molecule fluorescence and FRET measurements of conformational dynamics. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — Curmi supplies the biological systems in which quantum coherence is actually claimed to matter; a pT/sqrt(Hz)-class spin sensor capable of watching radical-pair or exciton dynamics in situ would be aimed at exactly the questions his structures raise. Preferred attribute present: genuine quantum-biology substrate rather than a quantum-flavoured metaphor.
