Dear Bernhard, Funnily enough we wanted to do precisely that yesterday and the kind folks at the PDBe sent us this csv file (attached, but small).
It is the result of a query in the PDBe/chem database of all residues for which the molecule type is "amino acid". Other than all the cases you are after it includes names longer than 1-letter which are derived from di-, tri- and tetra-peptides and several "X" residues which have the alpha-amino acid mainchain but sidechains which cannot be considered to be derived from natural amino acids. Hope this helps, Robert -- Dr. Robert Esnouf, University Research Lecturer and Head of Research Computing, Wellcome Trust Centre for Human Genetics, Roosevelt Drive, Oxford OX3 7BN, UK Emails: rob...@strubi.ox.ac.uk Tel: (+44) - 1865 - 287783 and rob...@esnouf.com Fax: (+44) - 1865 - 287547
