（1）除子囊菌Podosporaanserina产生的一种漆酶是四聚体外，其它漆酶一般是单一多肽，由约 500 个氨基酸组成。 Except that one kind of Lac created by Podosporaanserina is a tretramer, the other Lacs are generally single polypeptide, which is made up of about 500 amino acids. （2）Lac是一种含铜多酚氧化酶，能催化酚类物质的氧化还原反应，在木质素的生物降解中发挥着重要的作用。它是一类以O2为电子受体的蛋白酶，对其作用机理，目前研究较透彻的是其催化多酚化物，如氢醌等，此过程须经过四次单电子传递。 Lac is a kind of Cu-containing polyphenol oxidase. It can catalyze the redox reaction of phenols, and plays an important role in the biological degradation of lignin. It is a kind of protease whose electron acceptor is O2. As to its mechanism of action, at present what has been fully explored is that it can catalyze polyphenol compound, such as hydroquinone. This process needs four times’ single electron transfer. |

比较中式的英语表达，有些用词不准确： Except that one kind of Lac produced （一种生物产生的酶不用create这种词）by Podosporaanserina is a tretramer, the other Lacs are generally single polypeptide, consisting of about 500 amino acids. Lac is a kind of Cu-containing polyphenol oxidase. It can catalyze the redox reaction of phenols, and plays an important role in the biological degradation of lignin. It is a kind of protease whose electron acceptor is O2. With regard to its mechanism of action, at present what has been fully explored is that it can catalyze polyphenol compound, such as hydroquinone（这能算作用机制吗？仅仅是作用而已）. This process needs a single electron transfer for four times. 看来你很喜欢 kind of，其实在你所用的所有句子中，这个词组都是多余的，可以不要。 另外，at present what has been fully explored is that it can catalyze polyphenol compound, such as hydroquinone这句话本身没有问题，但太绕了，直接了当说结论就好了,例如：With regard to its mechanism of action, it has been well documented that it can catalyze polyphenol compound, such as hydroquinone. 供参考。 |
