guanidine hydrochloride |
in the absence of added guanidine hydrochloride, MM-CK activity slightly decreases with NaCl concentration up to 4 M, but a dramatic decline is observed above that value, with full inactivation at 4.5 M. When guanidine is added, curves with similar shapes are obtained but NaCl concentrations needed to inactivate the enzyme are shifted towards lower values |

Guanidinium chloride |
inhibitory, in presence of NaCl, increased inhibitory activity. Inactivation by NaCl is due to dissociation of dimeric creatine kinase into its constitutive subunits, and upon monomerization, the protein becomes more susceptible to guanidinium denaturing effect |

enzyme activity slightly decreases with NaCl concentration up to 4 M, and a dramatic decline is observed above that value, with full inactivation at 4.5 M. In presence of guanidinium chloride, inactivation occurs much earlier.
