Laser-induced alignment of nanoparticles and macromolecules for single-particle-imaging applications
Muhamed Amin, Jean-Michel Hartmann, Amit K. Samanta +1
Laser-induced alignment of particles and molecules was long envisioned to support three-dimensional structure determination using "single-molecule diffraction" with x-ray free-elec…
Predicting the Oxidation States of Mn ions in the Oxygen Evolving Complex of Photosystem II Using Supervised and Unsupervised Machine Learning
Muhamed Amin
Serial Femtosecond Crystallography at the X-ray Free Electron Laser (XFEL) sources enabled the imaging of the catalytic intermediates of the oxygen evolution reaction of Photosyste…
Toward understanding the S2-S3 transition in the Kok Cycle of Photosystem II: Lessons from Sr-Substituted Structure
Muhamed Amin, Divya Kaur, M. R. Gunner +1
Understanding the water oxidation mechanism in Photosystem II (PSII) stimulates the design of biomimetic artificial systems that can convert solar energy into hydrogen fuel efficie…
CMInject: Python framework for the numerical simulation of nanoparticle injection pipelines
Simon Welker, Muhamed Amin, Jochen Küpper
CMInject simulates nanoparticle injection experiments of particles with diameters in the micrometer to nanometer-regime, e.g., for single-particle-imaging experiments. Particle-par…
Probing redox potential for Iron sulfur clusters in photosystem I
Fedaa Ali, Medhat Shafaa. W, Muhamed Amin
Photosystem I is a light-driven electron transfer device. Available X-ray crystal structure from Thermosynechococcus elongatus, showed that electron transfer pathways consist of tw…
Microscopic force for aerosol transport
Nils Roth, Muhamed Amin, Amit K. Samanta +1
A key ingredient for single particle diffractive imaging experiments is the successful and efficient delivery of sample. Current sample-delivery methods are based on aerosol inject…
Comparing the binding interactions in the receptor binding domains of SARS-CoV-2 and SARS-CoV
Muhamed Amin, Mariam K. Sorour, Amal Kasry
COVID-19, since emerged in Wuhan, China, has been a major concern due to its high infection rate, leaving more than one million infected people around the world. Huge number of stu…
Variations in Proteins Dielectric Constants
Muhamed Amin, Jochen Küpper
Using a new semi empirical method for calculating molecular polarizabilities and the Clausius Mossotti relation, we calculated the static dielectric constants of dry proteins for a…
Controlled beams of shockfrozen, isolated, biological and artificial nanoparticles
Amit K. Samanta, Muhamed Amin, Armando D. Estillore +4
X-ray free-electron lasers (XFELs) promise the diffractive imaging of single molecules and nanoparticles with atomic spatial resolution. This relies on the averaging of millions of…
Thermodynamics of the S2-to-S3 State Transition of the Oxygen-Evolving Complex of Photosystem II
Muhamed Amin, Divya Kaur, Ke R. Yang +5
The room temperature pump-probe X-ray free electron laser (XFEL) measurements used for serial femtosecond crystallography provide remarkable information about the structures of the…
Robust and accurate computational estimation of the polarizability tensors of macromolecules
Muhamed Amin, Hebatallah Samy, Jochen Küpper
Alignment of molecules through electric fields minimizes the averaging over orientations, e. g., in single particle imaging experiments. The response of molecules to external ac el…
