Abstract

In Paracentrotus lividus embryos, treatment with zinc ions induces the synthesis of the two major stress proteins with the same molecular weight as those induced by heat shock. The developmental stages responsive to zinc ion treatment are the same as those responsive to heat shock. However, zinc treatment induces a longer lasting synthesis of the stress proteins, and, unlike heat shock, does not induce thermotolerance and does not inhibit synthesis of the bulk proteins.

摘要

在紫球海胆胚胎中，用锌离子处理会诱导合成两种主要应激蛋白，其分子量与热休克诱导产生的应激蛋白相同。对锌离子处理有反应的发育阶段与对热休克有反应的阶段相同。然而，锌处理诱导应激蛋白的合成持续时间更长，并且与热休克不同，它不会诱导耐热性，也不会抑制大量蛋白质的合成。
