Marvin and JChem + Proteax
Biochemfusion’s Proteax toolkit lets you work with protein sequence data in a chemically meaningful way. By supporting post-translational and chemical modifications Proteax can switch between sequence-oriented and structure-oriented molecular representations. Proteax is easily integrated in Java- and .NET-based systems, as well as native high-performance systems. Third-party vendors are currently using Proteax in combination with ChemAxon software to create systems that support a superior range of molecule sizes - from very small molecules to large biopharmaceutical proteins.
