\begin{Description}\relax
sysptmPTMTYPE maps a site to the type of posttranslational modifications (PTMs).
The site is consisted of SysPTM protein identifer, start position of PTM, 
and end position of PTM.

\begin{Examples}
\begin{ExampleCode}
 # Convert to a list
 xx <- as.list(sysptmPTMTYPE)
 # Get the values for a few keys
 if(length(xx) >= 3){
   xx[1:3]
 }
 
 ## For the reverse map sysptmPTMTYPE2SITE
 xx <- as.list(sysptmPTMTYPE2SITE)
 if(length(xx) > 0){         
     ## Get the first one
     xx[[1]]
 }
