Abstract
In conjunction with a new database system that efficiently organizes
the metabolic pathway data from various organisms,
we are developing computational methodologies using binary relations
and hierarchies of enzymes.
Biological knowledge integrated in the system includes genes,
gene products, chemical compounds, enzyme reactions and metabolic
pathway diagrams.
By automatically mapping the enzymes of a specific organism on the
pathway diagrams, it becomes possible to visualize the characteristic
features of the organism-specific metabolic pathways.
With the aid of the computational methodology implemented in the system,
it becomes again possible to analyze and investigate the pathways in terms
of their function and evolution.
In this paper, we describe the outline of the system and present new
biological features of metabolic pathways revealed by the system.
