Map site to the type of posttranslational modifications

Description

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.

Details

Mappings were based on data provided by: SysPTM (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 v1.1, 2008-11-20

Examples

 # 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]]
 }
