Publication Abstract from PubMed Time-resolved crystallography of biomolecules in action has advanced rapidly as methods for serial crystallography have improved, but the large number of crystals and the complex experimental infrastructure that are required remain serious obstacles to its widespread application. Here, millisecond mix-and-quench crystallography (MMQX) has been developed, which yields millisecond time-resolved data using far fewer crystals and routine remote synchrotron data collection. To demonstrate the capabilities of MMQX, the conversion of oxaloacetic acid to phosphoenolpyruvate by phosphoenolpyruvate carboxy-kinase (PEPCK) is observed with a time resolution of 40 ms. By lowering the entry barrier to time-resolved crystallography, MMQX should enable a broad expansion in structural studies of protein dynamics. Millisecond mix-and-quench crystallography (MMQX) enables time-resolved studies of PEPCK with remote data collection.,Clinger JA, Moreau DW, McLeod MJ, Holyoak T, Thorne RE IUCrJ. 2021 Aug 4;8(Pt 5):784-792. doi: 10.1107/S2052252521007053. eCollection, 2021 Sep 1.
