Nucleotide excision repair (NER) is a versatile system that deals with various bulky and helix-distorting DNA lesions caused by UV and environmental mutagens. Based on how lesion recognition occurs, NER has been separated into global genome repair (GGR) and transcription-coupled repair (TCR). The yeast Rad7-Rad16 complex is indispensable for the GGR sub-pathway. Rad7-Rad16 binds to UV-damaged DNA in a synergistic fashion with Rad4, the main lesion recognizer, to achieve efficient recognition of lesions. In addition, Rad7-Rad16 associates with Elc1 and Cul3 to form an EloC-Cul-SOCS-box (ECS)-type E3 ubiquitin ligase complex that ubiquitinates Rad4 in response to UV radiation. However, the structure and architecture of the Rad7-Rad16-Elc1-Cul3 complex remain unsolved. Here, we determined the structure of the Rad7-Elc1 complex and revealed key interaction regions responsible for the formation of the Rad7-Rad16-Elc1-Cul3 complex. These results provide new insights into the assembly of the Rad7-Rad16-Elc1-Cul3 complex and structural framework for further studies.

Crystallographic software which solves structures using algorithms and automated rapid search calculations to perform molecular replacement and experimental phasing methods.
View all literature mentionsA set of software programs that utilizes dual spaces algorithms for the determination of small and macromolecular crystal structures by single crystal X-ray and neutron diffraction. Libraries, extra files and environment variables are not required for the executables. SHELX is intended to be run on a command prompt but may be called from GUIs such as shelXle, Olex2, Oscail or WinGX, or hkl2map.
View all literature mentionsSoftware for macromolecular model building, model completion and validation, and protein modelling using X-ray data. Coot displays maps and models and allows model manipulations such as idealization, rigid-body fitting, ligand search, Ramachandran plots, non-crystallographic symmetry and more. Source code is available.
View all literature mentionsA Python-based software suite for the automated determination of molecular structures using X-ray crystallography and other methods. Phenix includes programs for assessing data quality, experimental phasing, molecular replacement, model building, structure refinement, and validation. It also includes tools for reflection data and creating maps and models. Phenix can also be used for neutron crystallography. Tutorials and examples are available in the documentation tab.
