Table 2 represents an evaluation of the alternative versions of the pathway of de novo Pyrimidine biosynthesis in B. subtilis.
The 1st column represents a combination of the enzymes an alternative version under consideration.
The 2nd column lists IDs particular ORFs in B. subtilis corresponding to the specific EC numbers from the column 1 (WIT IDs are used in this case).
The 3rd column displays the probability scores of occurrence of a particular alternative version of a pathway in a given organism. The scores are calculated according to the following algorithm:
 
2 + (EF - EM - 0.5 * ENS)
--------------------
(ET
 
EF  -- number of enzymes found in the genome
EM -- number of enzymes from particular version of a pathway missing in the genome
ENS -- number of enzymes that are not sequenced in any organisms and thus are impossible to recognize via conventional sequence analysis techniques
ET-- total number of enzymes in pathway

*Signature enzymes count double.
