The nucleotide sequence of the structural gene of nitrate reductase (n ar beta) has been determined from the filamentous, non-heterocystous cyanobacterium Oscillatoria chalybea. The nar beta gene encodes a protein of 737 amino acid residues, which shows 61% identity to nitrate reductase of the unicellular cyanobacterium Synechococcus sp. PCC 7942 and only weak homologies to different bacterial molybdoenzymes, such as nitrate reductases or formate dehydrogenases.
已从丝状、无异形胞的蓝细菌颤藻中确定了硝酸还原酶（narβ）结构基因的核苷酸序列。narβ基因编码一种由737个氨基酸残基组成的蛋白质，该蛋白质与单细胞蓝细菌聚球藻属PCC 7942的硝酸还原酶具有61%的同一性，与不同的细菌钼酶（如硝酸还原酶或甲酸脱氢酶）仅有微弱的同源性。
