The PDH requires the sequential action of five co-factors or co-enzymes for the combined action of dehydrogenation and decarboxylation to take place. These five are TPP (thiamine phosphate), FAD (flavin adenine dinucleotide), NAD (nicotinamide adenine dinucleotide), coenzyme A (denoted as CoA-SH ...
Acetyl-CoA synthetase activity is enzymatically regulated by lysine acetylation using acetyl-CoA or acetyl-phosphate as donor molecule Abstract The AMP-forming acetyl-CoA synthetase is regulated by lysine acetylation both in bacteria and eukaryotes. However, the underlying mechanism is poorly understood. ...
1. A process for preparing compounds of the formula I wherein R1 and R2 are each independently hydrogen, F, Cl, trifluoromethoxy, 2,2,2-trifluoroethoxy, trifluoromethyl, 2,2,2-trifluoroethyl or alkyl having 1, 2, 3 or 4 carbon atoms; R3 is Alk-R4 or trifluoromethyl; Alk is alkyl h...
Here, we report that NAOD contributes to the better adaptation of the parasite to nitrosative stress (NS) and that this function does not depend on NAOD catalytic activity. We also demonstrated that glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is detrimental to E. histolytica exposed to NS ...
Although the carboxylase preparation is relatively crude after the purification procedure outlined above, the elution from calcium phosphate gel was carried out with 1 .Oml of solution and therefore yielded a solution of enzyme that was concentrated enough for these studies. The sedimenta- tion of ...

The column was equilibrated with 50 mM phosphate buffer, pH 6.8, containing 150 mM NaCl. Proteins were eluted from the column at a flow rate of 1.0 ml/min at room temperature using a Waters 650 system (Waters Corp., Milford, MA). To induce oligomerization, proteins were preincubated with...
3b). According to the pH stability assay results, the relative activities were higher than 65% for the pH range starting from 4.0–7.0 and 5.0–7.0 after an incubation period of 1 h and 2 h, respectively (Fig. 3c). The enzyme was incubated with phosphate citrate buffer (pH 5.0) at ...
