NMR Structure of Haloferax volcanii DHFR
Structural highlights
Function[DYR_HALVD] Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis (By similarity). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedProteins from halophiles have adapted to challenging environmental conditions and require salt for their structure and function. How halophilic proteins adapted to a hypersaline environment is still an intriguing question. It is important to mimic the physiological conditions of the archae extreme halophiles when characterizing their enzymes, including structural characterization. The NMR derived structure of Haloferax volcanii dihydrofolate reductase in 3.5 M NaCl is presented, and represents the first high salt structure calculated using NMR data. Structure calculations show that this protein has a solution structure which is similar to the previously determined crystal structure with a difference at the N terminus of beta3 and the type of beta-turn connection beta7 and beta8.
