Winder, Frank G. (Trinity College, Dublin, Ireland). Peroxidatic activity of mycobacteria and relation to catalase. J. Bacteriol. 92:413-417. 1966.-Catalase from Mycobacterium smegmatis was purified about 50-fold. All fractions showed a ratio of peroxidatic activity to catalatic activity approximately the same as that of the crude extract, a ratio only about four times that given by catalase from Micrococcus lysodeikticus. This and other evidence strongly suggest that the peroxidatic activity of M. smegmatis is due to its catalase. Less complete evidence suggests that this is true in the case of Mycobacterium tuberculosis also. It is suggested that in the context of the mycobacteria the term "peroxidatic activity" should replace the term "peroxidase" unless evidence is found that a true peroxidase exists in these organisms.
温德，弗兰克·G.（爱尔兰都柏林三一学院）。分枝杆菌的过氧化物酶活性及其与过氧化氢酶的关系。《细菌学杂志》92:413 - 417。1966年。-耻垢分枝杆菌的过氧化氢酶被纯化了约50倍。所有组分的过氧化物酶活性与过氧化氢酶活性之比与粗提物大致相同，该比值仅约为溶壁微球菌过氧化氢酶的四倍。这一证据及其他证据有力地表明，耻垢分枝杆菌的过氧化物酶活性是由其过氧化氢酶引起的。不太完整的证据表明，结核分枝杆菌的情况也是如此。有人建议，在分枝杆菌的背景下，除非发现这些生物体中存在真正的过氧化物酶，否则“过氧化物酶活性”一词应取代“过氧化物酶”一词。
