gMol is an interactive visualization system used to display and manipulate 3-dimensional models of scientific data, such as molecular structures and surfaces. It contains both OpenGL and web browser widgets that enable flexible user interfaces.
Protein Data Bank transformed into an SQL database with a very powerful search engine and a rich web interface. The engine combines chemical, sequence and 3D structure searches. The interface provides statistics, sequence and 3D structure alignments.
