Topological classes within fold type I. The classification is based on defining the strands that form the core. The strands are numbered from the N-terminus to the C-terminus and read from left to right. Only the SAM/SAH domain is included. Bound SAM is shown as a ball and sticks, and the structures are represented in cartoon diagrams. The strands that form the core are colored in red. The labels list the PDB-ID followed by the topology. The corresponding two-dimensional topological arrangement is provided in Additional file 3. The figures were generated using PyMOL visualization software (http://www.pymol.org).
