Loop classification table Five tables of loop classes were constructed based on the types of loop. This number may vary in the same loop class. Root Mean Square Deviation of the superposed loops and their bracing secondary structure. It is used to quantify agreement but not for clustering. Consensus - Sequence Consensus within the loop class.
X denotes no sequence consensus.
The codes are explained in the table legend. Here is an example of the java picture. The table at the right side of the picture gives the PDB code and residue ID of these four loops. You may click the PDB code to check the PDB header lines of the protein.
