The BER structural biology and imaging resources—together with systems biology approaches—enable scientists to understand the relationships between plant and microbial genomes, protein structure and function, and environmental interactions important for bioenergy and environmental missions. A variety of techniques, many of which are available only at DOE User facilities, are available and can be used to probe target sizes of less than an Angstrom to millimeters across a range of temporal scales.BER’s support of structural biology and imaging user programs is designed to provide the scientific community access to world-class experimental tools and scientific and technical expertise in support of their research programs, including areas of BER mission relevance. Facilities are open to users from academia, national laboratories, the private sector, and research institutes. Access is most often obtained through peer-reviewed proposals, with no charge for users who intend to publish their results. For research that is not intended for publication, access is available on a cost-recovery basis.
