- Abstract
FOR conjugation of Blepharisma intermedium to take place interaction of soluble gamones with the cells is essential for union between complementary mating types I and II (refs 1 and 2). Type I cells excrete gamone 1 which transforms type II cells so that they can unite. Type II cells excrete gamone 2 which similarly transforms type I cells. Moreover, each gamone promotes the production of the other. Gamone 1, blepharmone, is a glycoprotein of molecular weight 20,000 (refs 3 and 4). Gamone 2, blepharismone, is calcium 3-(2′-formylamino-5′-hydroxybenzoyl) lactate5.
