Abstract
Alignment of the amino acid sequence of peptides obtained following digestion of Photobacterium leiognathi iron superoxide dismutase with the known sequence of Bacillus stearothermophilus manganese superoxide dismutase shows that the residues found to form ligands to the manganese are conserved in the iron enzyme. This indicates that the metal ligands in both proteins are identical.
摘要
用嗜热脂肪芽孢杆菌锰超氧化物歧化酶的已知序列对鱼发光杆菌铁超氧化物歧化酶进行消化后获得的肽的氨基酸序列比对表明，发现与锰形成配体的残基在铁酶中是保守的。这表明两种蛋白质中的金属配体是相同的。
