title: Temperature dependence of arginine kinase reaction in the tail muscle of live Sycionia ingentis as measured in vivo by 31P-NMR driven saturation transfer.
abstract: We have employed the driven 31P-NMR saturation transfer method to measure in vivo the temperature dependence of the forward and reverse unidirectional fluxes of the arginine kinase reaction in the tail muscle of a live shrimp, Sycionia ingentis. Our results indicated that neither the forward nor the reverse rate constants of this reaction were significantly temperature-dependent between 8 and 16 degrees C, in contrast to the kinetic characteristics of isolated arginine kinases.
