KEGG ENVIRON Database

KEGG ENVIRON is a collection of crude drugs, essential oils, and other health-promoting substances, which are mostly natural products of plants. Each KEGG ENVIRON entry is identified by the E number and is associated with the chemical component, efficacy information, and source species information whenever applicable. Currently, there are three major categories of KEGG ENVIRON as follows. As a related resource, the KEGG COMPOUND database contains environmental pollutants and other health-damagine substances.

About C/D/E Numbers

The C number, D number, and E number entries in KEGG COMPOUND, KEGG DRUG, and KEGG ENVIRON, respectively, are collected with the following criteria.
  • Single-component chemicals are stored in KEGG COMPOUND.
  • Multiple-component chemicals and crude materials are stored in KEGG ENVIRON.
  • Approved drugs in Japan, USA, and Europe are stored in KEGG DRUG.
  • Crude drugs listed in the Japanese Pharmacopoeia and the Japanese standards for non-Pharmacopoeial crude drugs are stored in KEGG DRUG.
Therefore, there are cases where the same substance is represented by D and C number entries or D and E number entries, which are cross-referenced in the Remark field. Note that in BRITE hierarchy files the D numbers are preferentially used.

Biosynthesis of Plant Natural Product

Plants are known to produce diverse chemical substances including those with medicinal and nutritional values. KEGG ENVIRON contains many such plant natural products. Towards better understanding of the links between genomes and chemical substances, our knowledge on the biosynthesis of plant natural products is accumulated in KEGG PATHWAY and is represented by regular pathway maps, a global map, and chemical structure transformation maps.

Microbial Degradation of Environmental Pollutants

Microorganisms are known to be capable of degrading diverse chemical substances including man-made chemicals in the environment, some of which are stored in KEGG COMPOUND. Towards better understanding of the links between genomes and chemical substances, our knowledge on the biodegradation of xenobiotic compounds is accumulated in KEGG PATHWAY and is represented by regular pathway maps, a global map, and a reaction module map.
