A new Rhea release is available, with 6989 unique reaction IDs.
Starting with this release, the Rhea database provides reactions including two new kinds of entities, namely:
A Rhea polymer is a ChEBI polymer with a specific abstract polymerization index.
A Rhea generic is a macromolecule such as a protein or nucleic acid whose functional groups are represented using entities from ChEBI.
More details are provided in the Rhea documentation.
The distribution files and web services have been modified to manage these new types of reaction participant.
