This is an announcement of the availability of a new molecular modeling program - Biomer, that is accessible over the web. It should be useful as an educational tool as well as a means to generate structures quickly and easily. It is written in Java, and version 1.0a has the following features:

• Model Builders for:
  • nucleic acids (DNA/RNA)
  • polypeptides
  • polysaccharides
• Interactive molecule editor with fragment libraries
• Implementation of the AMBER force field
• Geometry Optimization with steepest descent / conjugate gradient
• Simulated Annealing with molecular dynamics
• Reads / Writes PDB files
• Exports jpeg, gif, and ppm images
