Additional genes and associated reactions added to the model through bi-directional BLASTp homology searches.

aEncodes the phosphocarrier protein. The phosphoenolpyruvate-protein phosphotransferase component (MG429) was already included in the model.
b Forward referes to using the M. genitalium locus as the input sequence to be searched against other genomes.
c Reverse referes to using the locus of the other organism as the input sequence to be searched against the genome of M. genitalium.
