TLDR
The PHENIX software for macromolecular structure determination is described and its uses and benefits are described.
Abstract
Macromolecular X-ray crystallography is routinely applied to understand biological processes at a molecular level. How­ever, significant time and effort are still required to solve and complete many of these structures because of the need for manual interpretation of complex numerical data using many software packages and the repeated use of interactive three-dimensional graphics. PHENIX has been developed to provide a comprehensive system for macromolecular crystallo­graphic structure solution with an emphasis on the automation of all procedures. This has relied on the development of algorithms that minimize or eliminate subjective input, the development of algorithms that automate procedures that are traditionally performed by hand and, finally, the development of a framework that allows a tight integration between the algorithms.

Directed evolution of artificial metalloenzymes for in vivo metathesis

TL;DR: The compartmentalization and in vivo evolution of an artificial metalloenzyme for olefin metathesis is reported, which represents an archetypal organometallic reaction without equivalent in nature, with potential applications in, for example, non-natural metabolism.

High-resolution structure determination by continuous-rotation data collection in MicroED

TL;DR: An improved data collection protocol for MicroED is presented called 'continuous rotation', which enables data processing with the crystallographic software tool MOSFLM, which resulted in improved resolution for the model protein lysozyme.

Structure of photosystem II and substrate binding at room temperature

Iris D. Young, +72 more
- 21 Nov 2016 - 
TL;DR: Ammonia, a water analogue, has been used as a marker, as it binds to the Mn4CaO5 cluster in the S2 and S3 states, and this approach, together with a comparison of the native dark and 2F states, is used to discriminate between proposed O–O bond formation mechanisms.
