 Abstract: We introduce a liquid application method for time-resolved analyses (LAMA), an in situ mixing approach for serial crystallography. Picoliter-sized droplets are shot onto chip-mounted protein crystals, achieving near-full ligand occupancy within theoretical diffusion times. We demonstrate proof-of-principle binding of GlcNac to lysozyme, and resolve glucose binding and subsequent ring opening in a time-resolved study of xylose isomerase.

Project information

Project name : The authors thank D. Oberthuer (CFEL, DESY Hamburg) for the provision of the GlcNAc3 substrate immediately before data collection. The LAMA TR-SSX data were collected at beamline P14 and P14-2 (T-REXX) operated by EMBL Hamburg at the PETRA III storage ring (DESY, Hamburg, Germany). Construction of T-REXX was funded by the BMBF (Verbund Forschungsprojekt 05K16GU1). The authors are grateful to R. Dousza, L. Bultema and J. Besaw for their technical assistance during data collection. T-REXX beamtime was awarded as part of the EMBL BAG MX-660. The authors gratefully acknowledge the support provided by the Max Planck Society and the excellence cluster ‘The Hamburg Centre for Ultrafast Imaging—Structure, Dynamics and Control of Matter at the Atomic Scale’ of the Deutsche Forschungsgemeinschaft EXC 1074 project ID 194651731 (R.J.D.M.). P.M. was supported by the Alexander von Humboldt-Stiftung for postdoctoral researchers.
