The Rate-Limiting Enzyme regulation database (RLEdb) was developed to serve as a central repository of metabolic rate-limiting enzymes as well as their regulatory information include their related transcriptional factors, reversible phosphorylation sites and inhibitors.

Our database allows you to:

  1. searching and browsing the curated rate-limiting enzymes by their pathways, subcelluar localizations, expressed tissues and genome localization

  2. browsing regulatory information of rate-limiting enzymes including their related transcription factors, phosphorylation regulatory site and inhibitors

  3. systematic comparing the rate-limiting enzyme profiles between different organisms

  4. overview of all rate-limiting enzymes from each KEGG maps in a color-marked style

  5. systematic study of metabolic pathways regulation from transcription factor, phosphorylation or inhibitor aspects

We will maintain and update RLRdb regularly as more data and information become available. When using this resource, please cite:
