MetaCyc: A
multiorganism database of metabolic pathways and enzymes
Peter D. Karp
SRI
International
Objectives:
 |
Develop
a finely curated database of metabolic pathways and enzymes from a wide
variety of organisms, primarily microorganisms and plants that contains
a representative of every experimentally elucidated metabolic pathway.
|
 |
Propose
an initiative to determine sequences for the many biochemically
characterized enzymes for which no sequence has ever been determined. Such enzymes cannot at present be recognized
in a sequenced genome, and are not accessible to genetic engineering
techniques.
|
 |
Describe the
BioPAX standard for exchange of metabolic data.
|
Approach:
 |
Capture
experimentally elucidated pathways, reactions, chemical compounds, and
genes from the biomedical literature.
|
Accomplishments:
 |
MetaCyc
describes 1543 enzymes in 491 metabolic pathways derived from more than
200 organisms.
|
Impact:
 |
MetaCyc
provides a readily accessible comprehensive resource on microbial and
plant enzymes that can be metabolically engineered into other species.
|
 |
MetaCyc
is the reference database of pathways and enzymes that is used in
conjunction with SRI's metabolic pathway prediction program to predict
the metabolic network of an organism from its annotated genome.
Qualitative models of a metabolic network are an important step toward
metabolic engineering.

Abstract:
The
MetaCyc database (see URL http://MetaCyc.org/
) is a collection of metabolic pathways and enzymes from a wide variety
of organisms, primarily microorganisms and plants. The goal of MetaCyc
is to contain a representative sample of each experimentally elucidated
pathway, and thereby to catalog the universe of metabolism. MetaCyc
also describes reactions, chemical compounds, and genes. Many of the
pathways and enzymes in MetaCyc contain extensive information,
including comments and literature citations. SRI's Pathway Tools
software supports querying, visualization, and curation of
MetaCyc. MetaCyc serves two roles in metabolic engineering.
It is a readily accessible comprehensive resource on microbial and
plant enzymes that can be inserted into other species. In
addition, MetaCyc is the reference database of pathways and enzymes
that is used in conjunction with SRI's metabolic pathway prediction
program to predict the metabolic network of an organism from its
annotated genome. Qualitative models of a metabolic network are
an important step toward metabolic engineering.
The
talk will propose an initiative to determine sequences for the many
biochemically characterized enzymes for which no sequence has ever been
determined. Such enzymes cannot at present be recognized in a
sequenced genome, and are not accessible to genetic engineering
techniques.
The
talk will present a status report on the BioPAX standard for exchange
of metabolic information.
