Abstract Background We present a computational pathway analysis of the human genome that assigns enzymes encoded therein to predicted metabolic pathways. Pathway assignments place genes in their larger biological context and are a necessary first step toward quantitative modeling of metabolism. Results Our analysis assigns 2 709 human enzymes to 896 bioreactions 622 of the enzymes are assigned roles in 135 predicted metabolic pathways. The predicted pathways closely match the known nutritional requirements of humans. This analysis identifies probable omissions in the human genome annotation in the form of 203 pathway holes missing enzymes within the predicted pathways . We have identified putative genes to fill 25 of these holes. The predicted human metabolic map is described by a Pathway Genome Database called .
