Abstract
Phosphorus resonances consistent with phosphoarginine and ATP were observed in the in vivo 31P-nuclear magnetic resonance (NMR) spectra of infective larvae of Haemonchus contortus. The level of phosphoarginine quickly declined when nematode suspensions were purged with nitrogen and was restored upon return to aerobic conditions. Saturation transfer NMR demonstrated forward and reverse exchange of phosphorus between phosphoarginine and ATP.
摘要
在捻转血矛线虫感染性幼虫的体内31P-核磁共振（NMR）光谱中观察到了与磷酸精氨酸和ATP一致的磷共振。当用氮气吹扫线虫悬浮液时，磷酸精氨酸水平迅速下降，恢复到有氧条件后又恢复。饱和转移NMR表明了磷酸精氨酸和ATP之间磷的正向和反向交换。
