CCP4 (Collaborative Computational Project No. 4)

CCP4 (Collaborative Computational Project No. 4) is a global consortium that develops and maintains software tools for determining the 3D structures of biological molecules, primarily proteins and DNA, using X-ray crystallography. It provides researchers with integrated programs and resources for processing raw experimental data, building atomic models, and validating structures. CCP4 facilitates collaboration among scientists and standardizes methods, making the complex process of deciphering molecular shapes more accessible, accurate, and efficient. Its goal is to advance understanding of biological functions and aid drug discovery through high-quality structural data.
