Activating Compound
Activating Compound on EC 2.7.4.14 - UMP/CMP kinase
Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
doxorubicin
binding of doxorubicin to the enzyme (CMPK1) activates the phosphorylation of CMP, dCMP, and UMP. Doxorubicin might bind to the nonactive site of CMPK1 and regulate its activity with magnesium
NADPH
-
NADPH-dependent activation system is composed of at least two protein factors: one is heat-stable and the other is indistinguishable from NADPH-dependent disulfide reductase
2-mercaptoethanol
-
at 5 mM: reduction in molecular weight from approximately 53000 Da to 17000 Da. This low molecular weight form is partially active in the presence of 2-mercaptoethanol. In absence of 2-mercaptoethanol the low molecular weight form is inactive. At 50 mM: full reactivation of the CMP(ATP) kinase activity followed by dCMP(ATP) and CMP(dCTP)
thioredoxin
-
activity is strictly dependent upon sulfhydryl reducing agents. Reduced thioredoxin is by far the most effective
