Cordycepin and pentostatin biosynthesis gene identified through transcriptome and proteomics analysis of Cordyceps kyushuensis Kob.

Cordyceps kyushuensis is the only species of cordyceps growing on the larvae of Clanis bilineata Walker, and has been demonstrated that there are lots of pharmacological components including cordycepin. Cordycepin shows lots of pharmacological action but it could be converted to 3'-deoxyinosine by adenosine deaminase in vivo, which weakens the efficiency of cordycepin. That pentostatin, which has been reported to inhibit adenosine deaminase, combining cordycepin could enhance the efficiency of cordycepin in vivo.

Enediyne antitumor antibiotic maduropeptin biosynthesis featuring a C-methyltransferase that acts on a CoA-tethered aromatic substrate.

The enediyne antitumor antibiotic maduropeptin (MDP) is produced by Actinomadura madurae ATCC 39144.
