JTools is a web-based toolkit, which can help the molecular biologists to more efficiently use JCDB. Now JTools have provided three tools of retrieving sequence (Sequence Retrieving), converting ID (ID Conversion) and constructing network (Network Construction).

Sequence Retrieving
ID Conversion
input a list of ID(s)

JCDB to others or others to JCDB

Network Construction
input a list of JCDB ID(s)

interaction between genes

network result (this can be input for Cytoscape)
