During the development of fruit bodies of Schizophyllum commune there is a minimum 10- to 15-fold increase in amylase activity. There is little or no activity in homokaryons or dikaryons. The activity is found early after the onset of morphogenesis and increases until the fruit bodies are mature. Inhibition studies with CO(2) indicate that the activity is directly associated with fruiting, as a change from fruiting to vegetative growth of the dikaryotic mycelium leads to a loss in activity, whereas the already formed fruit bodies show no loss. The activity is unaffected by the level of glucose in the medium. Evidence is presented, based on the mode of starch degradation and on yield and inhibition studies, that the enzyme is a glucoamylase.
在裂褶菌子实体发育过程中，淀粉酶活性至少增加10至15倍。同核体或双核体中几乎没有或完全没有活性。该活性在形态发生开始后不久就被发现，并一直增加直到子实体成熟。用二氧化碳进行的抑制研究表明，该活性与结实直接相关，因为双核菌丝体从结实生长转变为营养生长会导致活性丧失，而已经形成的子实体则没有活性丧失。该活性不受培养基中葡萄糖水平的影响。基于淀粉降解模式以及产量和抑制研究提供的证据表明，该酶是一种糖化酶。
