Supplemental Research Data

1. A list of PDB chains in alphanumeric order that comprise the IDSB-rich and IDSB-poor subset of sequence non-homologous protein chains 2. Frequency distribution of chain lengths for IDSB-rich and -poor chains. Lengths were discretised with a bin size of 10 residues. 3. A list of IDSB loop sizes in IDSB-rich protiens and IDSB-poor proteins and their frequency in the dataset. 4. A list of IDSB loop sizes in protein chains with a 1-2 3-4 5-6 (III) IDSB bonding pattern and their frequency in the dataset. 5. SCOP folds associated with loop sizes, showing a sample of the results found for SCOP folds. In the <20 residue range there were many overlapping continua of folds. 6. Relationship between the number of IDSBs per protein chain and median chain length, for all chains, IDSB-rich and IDSB-poor. On average, for each additional IDSB, the IDSB-rich median chain length increased by 15 residues, and the IDSB-poor by 25 residues.
