As always, the speaker is happy to receive questions;  e-mail your questions during the talk to sciencequestions@ess.eu and they will be addressed at the end of the seminar.


Micromanagement of amino acid transporters

Biomembranes and membrane transport are fundamental components of life, establishing order in chaotic surroundings. Active transporters help compounds travel against (electro)chemical gradients to reach their goal. We study such transporters that couple uphill transport of amino acids and neurotransmitters with the downhill influx of Na+ into cells. Using serial synchrotron crystallography approaches, we have determined structures of human and bacterial amino acid transporters and are also preparing for time-resolved studies. Aiming for analysis of hydrogen-bonding networks, we explore growth of large membrane protein crystals for neutron diffraction studies

About the Joint ESS – MAX IV Science Colloquia
Co-organised by MAX IV Laboratory and ESS, the aim of these colloquia is to bring the science made possible by neutrons and synchrotron radiation into focus, and to bring people at ESS and MAX IV and the local science community together. They are held every month, with the venue alternating between MAX IV and ESS. Always on a Wednesday, always at 15:15 – and always with coffee and sweets served at 15:00. Due to the need for social distancing we are temporarily shifting the colloquia to a web-based platform, and although we will miss the face-to-face interaction we hope that this can attract a wider audience than usual!
