Abstract
In Chlamydomonas reinhardii the reduction of nitrate to ammonia occurs in two independent enzymatic steps: 1. the two-electrons reduction of nitrate to nitrite catalyzed by NADH-nitrate reductase, and, 2. the six-electrons reduction of nitrite to ammonia catalyzed by ferredoxin-nitrite reductase. Both enzymes have been purified and characterized, and some of their properties have been studied.
摘要
在莱茵衣藻中，硝酸盐还原为氨的过程分两个独立的酶促步骤进行：1. 由NADH-硝酸盐还原酶催化的硝酸盐双电子还原为亚硝酸盐；2. 由铁氧还蛋白-亚硝酸盐还原酶催化的亚硝酸盐六电子还原为氨。这两种酶均已被纯化并进行了表征，且对它们的一些特性进行了研究。
