A large change made in the course of remediation was the distinction between ribonucleotides (A, C, G, I, T, U) and deoxyribonucleotides (DA, DC, DG, DI, DT, DU). The main reason for getting unremediated PDB files is that when the remediated PDB files contain DNA, Protein Explorer (and perhaps some other software) does not display the DNA properly. If the PDB file does not contain DNA (protein, RNA, solvent and ligands are OK), you probably don't need the unremediated file. | A large change made in the course of remediation was the distinction between ribonucleotides (A, C, G, I, T, U) and deoxyribonucleotides (DA, DC, DG, DI, DT, DU).

Use the interface at [http://www.umass.edu/microbio/chime/pe_beta/pe/protexpl/unremed.htm Eric Martz's UMASS site] to get unremediated pdb files from the RCSB Protein Data Bank via FTP. | As detailed [http://www.rcsb.org/pdb/static.do?p=general_information/news_publications/news/news_2007.html#20070904 here], the unremediated PDB archive from before August 1, 2007 remains available at [ftp://ftp.rcsb.org via ftp at the RCSB Protein Data Bank].<br> | ||

These files come back in a compressed form. Eric Martz's site lists Winzip as an alternative for PC but this program is not free once a trial period expires; Stuffit expander failed to uncompress such a file on a PC although Eric lists it as useful on Macs. | |||
