Crystallising the Truth
mosquito® Crystal: Key for Identifying the Structure of Intracellular Glutathione Transport ProteinTTP LabTech today announced the availability for download of an application note entitled “mosquito® Crystal for the rapid screening and optimisation of crystallisation conditions of the bacterial periplasmic binding protein, HbpA and the elucidation of its role as a glutathione import protein”. The revolutionary design of the mosquito® Crystal offers accurate and rapid nanolitre dispensing of even the most viscous liquids (from 50 nL to 1.2 µL). In addition, its low cost disposable tips guarantee zero cross contamination between samples, making mosquito Crystal the ideal platform for flexible dispensing in crystallography.
Glutathione is one of the most important antioxidant molecules produced by the body. With roles extending from growth and repair to molecular detoxification and excretion, it is ubiquitous in all cells whether eukaryotic or prokaryotic. Although GSH is made constitutively within eukaryotic cells, bacteria are auxotrophic for GSH and need to acquire this molecule by import mechanisms. Bacteria which are unable to import GSH are more susceptible to oxidative and disulphide stress, reducing their pathogenicity and ability to colonise certain host niches within the body. An understanding of such bacterial import proteins may therefore be useful for understanding mechanisms of pathogenicity and infection. This application note describes how the mosquito Crystal was used to dispense 100 nL crystallisation droplets (50 nL protein sample and 50 nL crystallisation condition). This allowed rapid and efficient screening of almost 2000 crystallisation conditions, ultimately resulting in the successful crystallisation and identification of a novel GSH import protein.

Crystal oscillators are electronic oscillator circuits which employ the mechanical reverberation of a resonating crystal of piezoelectric substantial to make an electrical signal by way of an exact frequency. This frequency is frequently employed to monitor time, like within quartz wristwatches, to give a steady clock signal for advanced integrated circuits as well as to settle frequencies for receivers as well as radio transmitters. Crystal oscillators are the fundamental parts…
