What is hidden in the darkness? Characterization of AlphaFold structural space

Abstract

AbstractThe recent public release of the latest version of the AlphaFold database has given us access to over 200 million predicted protein structures. We use a “shape-mer” approach, a structural fragmentation method analogous to sequencek-mers, to describe these structures and look for novelties - both in terms of proteins with rare or novel structural composition and possible functional annotation of under-studied proteins. Data and code will be made available athttps://github.com/TurtleTools/afdb-shapemer-darkness
