We have constructed a non-homologous database, termed the Integrated
Sequence-Structure Database (ISSD) which comprises the coding sequences of
genes, amino acid sequences of the corresponding proteins, their secondary
structure and straight phi,psi angles assignments, and polypeptide backbone
coordinates. Each protein entry in the database holds the alignment of
nucleotide sequence, amino acid sequence and the PDB three-dimensional
structure data. The nucleotide and amino acid sequences for each entry are
selected on the basis of exact matches of the source organism and cell
environment. The current version 1.0 of ISSD is available on the WWW at
http://www.protein.bio.msu.su/issd/ and includes 107 non-homologous
mammalian proteins, of which 80 are human proteins. The database has been
used by us for the analysis of synonymous codon usage patterns in mRNA
sequences showing their correlation with the three-dimensional structure
features in the encoded proteins. Possible ISSD applications include
optimisation of protein expression, improvement of the protein structure
prediction accuracy, and analysis of evolutionary aspects of the nucleotide
sequence-protein structure relationship.
