Popis: The phosphodiesterase from calf spleen (EC 3.1.4.18) was immobilized on several supports. Some properties of the most suitable enzyme support system--calf spleen phosphodiesterase bound to agarose-Concanavalin A--were investigated, e.g., pH dependence, influence of ionic strength of the buffer medium, and Zn2+-ion inhibition. The immobilized spleen phosphodiesterase showed about 60% of the activity of the free enzyme; the activity toward several oligonucleotide test substrates was unchanged for two months.
