Abstract

We report a microfluidic approach for de novo protein structure determination via crystallization screening and optimization, as well as on-chip X-ray diffraction data collection. The structure of phosphonoacetate hydrolase (PhnA) has been solved to 2.11 Å via on-chip collection of anomalous data that has an order of magnitude lower mosaicity than what is typical for traditional structure determination methods.
