Annotation of probe ids by enzyme commission number

Description

hu6800ENZYME mappes probe ids to enzyme commission numbers corresponding to the products of the genes represended by the probe ids

Details

This is an environment object with key and value pairs. Keys are probe ids and values are the corresponding enzyme commission numbers. Values are vectors of length 1 or greater depending on whether a given probe id can be associated with only one or more enzyme commission numbers.

NAs are assigned to probe identifiers that can not be associated with any enzyme commission numbers. Mappings between probe ids and enzyme ids were obtained through their mappings to LocusLink ids.

Mappings between probe ids and enzyme ids were obtained using files provided by:

Examples

        # Convert to a list
        xx <- as.list(hu6800ENZYME)
        # Remove probe ids that do not map to any enzyme EC number
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
        # Gets the enzyme commission numbers for the first five
        #probes
        xx[1:5]
        # Get the first one
        xx[[1]]
