Multiple forms of one enzyme occur in a wide variety of microorganisms. Their synthesis is often dependent on culture characteristics such as medium composition, physico-chemical parameters, culture age and the presence of inducing or inhibiting agents. Multiform enzymes increase the capability of the producing organism to adapt to and cope with a wide variety of environmental changes, such that the physiological advantages outweigh the apparent wasteful hyperproduction of multiple forms of one enzyme.
一种酶的多种形式存在于各种各样的微生物中。它们的合成通常取决于培养特性,如培养基成分、理化参数、培养时间以及诱导剂或抑制剂的存在。多形式酶提高了产生菌适应和应对多种环境变化的能力,因此其生理优势超过了一种酶多种形式明显的过度产生所带来的浪费。
