Cd2+ conspicuously inactivates the activity of the muscle-type enzyme in a first-order kinetic process and exhibits non-competitive inhibition with creatine and ATP. Cd2+ induces tertiary structure changes in enzyme PSCKM with exposure of hydrophobic surfaces. The addition of osmolytes, such as glycine and proline, partially reactivates the enzyme. Molecular dynamics and docking simulations between PSCKM and Cd2+ show that Cd2+ blocks the entrance of ATP to the active site of the enzyme, computational modeling, overview

accumulation in patients affected by short-chain acyl-CoA dehydrogenase deficiency and other diseases. Ethylmalonic acid inhibits the activity of respiratory chain complexes and also inhibits creatine kinase at concentrations o 1 mM and 5 mM
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

L-lysine
-
total and cytosolic creatine kinase activities are significantly inhibited by L-lysine, in contrast to the mitochondrial isoform which is not affected, the inhibitory effect of L-lysine on total creatine kinase activity is totally prevented by reduced glutathione
L-valine
-
branched chain alpha-amino acids bind at the active site, competitive inhibition mechanism against substrates phosphocreatine and ADP, inhibition kinetics
Lactic acid
-
induces dissociation of enzyme dimer and unfolding of the enzyme at 0.8 mM, but no aggregation at 25°C or 40°C even at high protein concentrations, inactivation kinetics
Pb2+
-
lead inhibits in vitro the cytosolic and mitochondrial creatine kinase activity at 0.2 mM and that this inhibition is prevented by addition cysteamine to the assay at 0.1 mM and 0.5 mM final concentration
phosphate
-
competitive against ATP and phosphocreatine, noncompetitive against ADP and creatine
sodium barbital
-
slow inactivation of enzyme that can be reversed by dilution. Sodium barbital may compete mainly with creatine, but also with ATP, for inhibition
sulfate
-
competitive against ATP and phosphocreatine, noncompetitive against ADP and creatine
trans-[RuCl2(3-pyridinecarboxylic acid)4]
-
administration at 180.7 micromol/kg, inhibition of creatine kinase activity in hippocampus, striatum, cerebral cortex, heart and skeletal muscle. No effect on enzyme in vitro
Acrylamide
-
significantly inactivate screatine kinase and glutathione S-transferase and deplete glutathione. When the dietary constituents, tea polyphenols, resveratrol, and diallyl trisulfide are cotreated with acrylamide, all of them can effectively recover the activities of creatine kinase
Acrylamide
-
CK-BB is kinetically reversibly inactivated by acrylamide accompanied by the disruption of the hydrophobic surface, complete inhibition at 800 mM
cystine
-
inhibits creatine kinase activity possibly by oxidation of the sulfhydryl groups of the enzyme. Considering that creatine kinase like other thiol-containing enzymes, is crucial for energy homeostasis and antioxidant defenses, the enzymes inhibition caused by cystine released from lysosomes could be one of the mechanisms of tissue damage in patients with cystinosis
cystine
-
cystine inhibited the enzyme activity in a dose- and time-dependent manner and cysteamine prevents and reverses the inhibition caused by cystine, suggesting that cystine inhibits creatine kinase activity by oxidation of the sulfhydryl groups of the enzyme; dose- and time-dependent inhibition, cysteamine prevents and reverses this inhibition
guanidinium hydrochloride
0.1-3.0 M, under both conditions, the tag-free enzyme shows the lowest degree of aggregation, followed by His-tagged CK, and Fc-III-tagged CK has the highest degree of aggregation
guanidinium hydrochloride
inactivation mechanism of wild-type and mutant enzymes, overview
guanidinium hydrochloride
-
first dissociation of subunits, then unfolding into random coil
iodoacetamide
-
70.9% inhibition of the atypical ubiquitous mitochondrial enzyme, 74.6% inhibition of the typical ubiquitous mitochondrial enzyme
NaCl
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. 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; 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
SDS
-
strongly inhibits the CK-BB activity in a noncompetitive manner, although almost all the activity is eliminated by SDS CK-BB is never completely inactivated (4% to 5% activity is still sustained), regardless of increased incubation time or SDS concentration
transition state analogue complex
-
consists of creatine, MgADP, and planar ions such as nitrate, nitrite, and formate, binding structure
-
transition state analogue complex
-
creatine, MgADP-, and planar ions such as nitrate, nitrite, and formate
-
Zn2+
-
Zn2+ may induce CK-BB inactivation and misfolding, when the Zn2+ concentration is 0.4 mM, CK-BB activity is completely abolished
