The MA-dictionary provides the data representation for describing structural models of macromolecules derived from computational methods.

These structural models are archived in the Model Archive. These models may be derived from already existing structural templates (also known as homology modeling or comparative modeling methods) or can be obtained from ab initio modeling methods.

The MA-dictionary is an extension of the PDBx/mmCIF dictionary. The PDBx/mmCIF dictionary is used by the wwPDB to archive structural models of macromolecules determined using X-ray crystallography, NMR spectroscory and three-dimensional Electron Microscopy.

You can’t perform that action at this time.
