\keyword{datasets}{PFAMPDB2AC}
\begin{Description}\relax
This is an R object that always contains mappings from a PDB ID to a
PFAM accession (AC)
\end{Description}
\begin{Details}\relax
The PFAM accession number has been attached to the PDB IDs in this object.

\begin{Examples}
\begin{ExampleCode}

        #To map from PDB to PFAM IDs:
        x <- PFAMPDB2AC
        # Get the PDB identifiers that are mapped to a PFAM ID
        mapped_keys <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_keys])
        if(length(xx) > 0) {
          # Get the PDB ID for the first five CAZYs
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
