+== Function ==
+[https://www.uniprot.org/uniprot/AA2AR_HUMAN AA2AR_HUMAN] Receptor for adenosine. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase.[https://www.uniprot.org/uniprot/C562_ECOLX C562_ECOLX] Electron-transport protein of unknown function.

+== Publication Abstract from PubMed ==
+Despite recent advances in cryo-electron microscopy and artificial intelligence-based model predictions, a significant fraction of structure determinations by macromolecular crystallography still requires experimental phasing, usually by means of single-wavelength anomalous diffraction (SAD) techniques. Most synchrotron beamlines provide highly brilliant beams of X-rays of between 0.7 and 2 A wavelength. Use of longer wavelengths to access the absorption edges of biologically important lighter atoms such as calcium, potassium, chlorine, sulfur and phosphorus for native-SAD phasing is attractive but technically highly challenging. The long-wavelength beamline I23 at Diamond Light Source overcomes these limitations and extends the accessible wavelength range to lambda = 5.9 A. Here we report 22 macromolecular structures solved in this extended wavelength range, using anomalous scattering from a range of elements which demonstrate the routine feasibility of lighter atom phasing. We suggest that, in light of its advantages, long-wavelength crystallography is a compelling option for experimental phasing.
