Protean 3D - Software for Exploring Macromolecular
Structure, Motion, and Function


Protean 3D is Lasergene's application for exploring macromolecular structure, motion, and function. Rich, synchronized graphical views allow you to see the 3D molecular structure, the annotated sequence, and the analysis of applied prediction methods simultaneously, enabling easy identification

and analysis of secondary structure elements. Protean 3D also provides access to the Motion Library, where you can browse and search over 300 animated and annotated macromolecular conformational changes, and to NovaFold, which allows you to predict three-dimensional structures for protein sequences. To learn more, see the Features or Resources tab below.
