The alternative-oxidase-mediated succinate oxidase activity of Neurospora crassa decreases drastically when mitochondria are fractionated into submitochondrial particles or treated with deoxycholate. The activity, however, can be completely restored in the presence of nucleoside 5'-monophosphates. The purine nucleoside 5'-monophosphates are more effective than the pyrimidine homologues. 5'-GMP gives a 10-fold stimulation of the alternative-oxidase-mediated succinate oxidase activity in submitochondrial particles. A comparison is made with the results obtained earlier with Moniliella tomentosa [Hanssens & Verachtert (1976) J. Bacteriol. 125, 825--835; Vanderleyden, Van Den Eynde & Verachtert (1980) Biochem. J. 186, 309--316].
当粗糙脉孢菌的线粒体被分级分离成亚线粒体颗粒或用脱氧胆酸盐处理时,交替氧化酶介导的琥珀酸氧化酶活性会急剧下降。然而,在核苷5'-单磷酸存在的情况下,该活性可以完全恢复。嘌呤核苷5'-单磷酸比嘧啶同系物更有效。5'-鸟苷酸能使亚线粒体颗粒中交替氧化酶介导的琥珀酸氧化酶活性提高10倍。并与之前用棉状丛赤壳菌得到的结果进行了比较[Hanssens & Verachtert (1976) J. Bacteriol. 125, 825 - 835;Vanderleyden, Van Den Eynde & Verachtert (1980) Biochem. J. 186, 309 - 316]。
