Summary
The DMAB-nitrite method for tryptophan containing proteins andβ-GPase activity has been studied in the cells of the cortex adjoining the haustonal cells ofCuscuta pentagona A strong positive reaction with DMAB-nitrite method points to a similarity between these cells and the animal ones secreting pepsidases. Aβ-GPase activity has been also found in the parasite cells in contact with the host stem. A protein rich in tryptophan as well as theβ-GPase activity might to be involved in the lysis of the host tissues.
