CCPlus-PDB CCPlus-AlphaFold Statistics Documentation

Welcome to CC+, a relational database of coiled-coil structures!

With the recent advent of AlphaFold and the predicted structures, the number of This database has been developed to help probe our understanding of the sequence-to-structure relationships in coiled-coil protein structures. To cite the database — published here — please refer to Testa et al. NAR, 2008. To cite the Periodic Table of Coiled-Coil Protein Structures, please refer to Moutevelis & Woolfson, JMB, 2008.
