The protein KUD-PC and process for its preparation

摘要

The protein KUD-PC which has the properties defined in Claim 1 has antitumour activity. The substance is obtained by cultivating a microorganism which produces KUD-PC in a nutrient medium and isolating the produced substance from the culture broth. The strain Streptosporangium pseudovulgalae PO-357, FERM-P No. 3571, has been found to be a microorganism particularly suitable for this purpose.
