\HeaderA{sysptmIDs}{Map SysPTM protein identifiers to external identifiers}{sysptmIDs}
\begin{Description}\relax
sysptmIDs maps SysPTM protein identifiers to external protein identifiers.
\end{Description}
\begin{Details}\relax
Each SysPTM protein identifier maps to a named vector containing protein
identifiers from public databases, such as Swiss-Prot, IPI, NCBI RefSeq, and
so on. The vector name corresponds to the public database.

Mappings were based on data provided by: SysPTM (\url{http://www.biosino.org/papers/SysPTM/Current/ptm ; http://www.biosino.org/papers/SysPTM/Current/name ; http://www.biosino.org/papers/SysPTM/Current/Protein_ID_equal}) on

\begin{Examples}
\begin{ExampleCode}
     # Convert to a list
     xx <- as.list(sysptmIDs)
     xx <- xx[!is.na(xx)]
     if(length(xx) > 0){
         xx[1:5]
     }
\end{ExampleCode}
