# Unraveling protein catalysis through neutron diffraction

## TL;DR

This paper explains how neutron diffraction helps study hydrogen atoms in enzymes, improving understanding of protein structures and reactions.

## Contribution

The paper highlights new neutron diffraction techniques and instrumentation developments for detailed protein analysis.

## Key findings

- Neutron diffraction reveals hydrogen atom positions in proteins and water.
- New instrumentation at ORNL enhances neutron-based structural biology capabilities.

## Abstract

Neutron diffraction provides a sophisticated, non-destructive means for the the atomic-resolution analysis of individual hydrogen atoms in enzymes. Here we describe how the precise location of protein and water hydrogen atoms using neutron diffraction provides a more complete description of the atomic and electronic structures of proteins, enabling key questions concerning enzyme reaction mechanisms, molecular recognition and binding and protein-water interactions to be addressed. We will briefly describe the capabilities that are available for neutron- based structural biology at ORNL, with special focus on the current upgrades and development of new instrumentation and software for neutron protein crystallographic analysis.
