abstract = {We introduce the spitrobot, a protein crystal plunger,
enabling reaction quenching via cryo-trapping with a
time-resolution in the millisecond range. Protein crystals
are mounted on canonical micromeshes on an electropneumatic
piston, where the crystals are kept in a humidity and
temperature-controlled environment, then reactions are
initiated via the liquid application method (LAMA) and
plunging into liquid nitrogen is initiated after an
electronically set delay time to cryo-trap intermediate
states. High-magnification images are automatically recorded
before and after droplet deposition, prior to plunging. The
SPINE-standard sample holder is directly plunged into a
storage puck, enabling compatibility with high-throughput
infrastructure. Here we demonstrate binding of glucose and
2,3-butanediol in microcrystals of xylose isomerase, and of
avibactam and ampicillin in microcrystals of the extended
spectrum beta-lactamase CTX-M-14. We also trap reaction
intermediates and conformational changes in macroscopic
crystals of tryptophan synthase to demonstrate that the
spitrobot enables insight into catalytic events.},
