The Transporter substrate database (TSdb) was developed to serve as a central repository of formated substrate information of transporters as well as their annotation. Most characteristic feature for our database is all the substrates are mapped to KEGG ligand compound database, thus it is easy to map all the substrate to the KEGG pathway.

Our database allows you to:

  1. search and browse the transporter by their substrates and organisms.

  2. get an overview for all the transporter substrate in a pathway.

  3. crosslink the formated substrate to other compound or metabolic pathway.

  4. query the gene interaction relations for transporters.

  5. discover the potential regulatory mechanisms among the transporter substrate and their inhibited metabolic enzymes.
