\HeaderA{PFAMPDB}{Mappings from a PFAM Accession number to a PDB ID}{PFAMPDB}
\keyword{datasets}{PFAMPDB}
\begin{Description}\relax
This is an R object that always contains mappings from a PFAM
accession (AC) to a PDB ID
\end{Description}
\begin{Details}\relax
The PDB ID along with the start point and end point have been attached
to the PFAM accessions in this object.

single worldwide repository for the processing and distribution of 3-D
biological macromolecular structure data.  Reference: H.M. Berman,

\begin{Examples}
\begin{ExampleCode}

        #To map from PFAM to PDB:
        x <- PFAMPDB
        # Get the PFAM identifiers that are mapped to a PDB
        mapped_keys <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_keys])
        if(length(xx) > 0) {
          # Get the PDB info for the first five PFAM IDs
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
