NAD-dependent malic enzyme (EC 1.1.1.39) was obtained from isolated mitochondria of cauliflower buds (Brassica oleracea L., var. botrytis). The NAD-linked activity is accompanied by a minor NADP-linked activity. Some contaminant NADP-malic enzyme from the supernatant and the plasma membrane is usually present in crude mitochondrial preparations. NAD-dependent malic enzyme has been purified 38-f...
sulfonic acid functionalized sba-15 (sba-pr-so3h) with pore size 6 nm as an efficient heterogeneous nanoporous solid acid catalyst exhibited good catalytic activity in the biginelli-like reaction in the synthesis of spiroheterobicyclic rings with good yield and good recyclability. spiro-pyrimidinethiones/spiro-pyrimidinones-barbituric acid derivatives were synthesized in a simple and efficient ...
Continuous assay of the soluble and inducible tryptophan pyrrolase (L-tryptophan : Hz02 oxidoreductase, EC 1.11.1.4) by direct spectrophotometry in the particle-free supcrnatant fraction of liver (1) would be a desirable alternative to t,he usual assay in whole liver homogenates (2) for studies of the adaptive variations of the concentration of this enzyme, but it is uncertain whether the total...
Telomeres serve the dual function of protecting chromosomes from genomic instability as well as protecting the ends of chromosomes from DNA damage machinery. The enzyme responsible for telomere maintenance is telomerase, an enzyme capable of reverse transcription. Telomerase activity is typically limited to specific cell types. However, telomerase activation in somatic cells serves as a key ste...
Protein kinase C (PKC) is activated by lipid second messengers or redox action, raising the question whether these activation modes involve the same or alternate mechanisms. Here we show that both lipid activators and oxidation target the zinc-finger domains of PKC, suggesting a unifying activation mechanism. We found that lipid agonist-binding or redox action leads to zinc release and disassem...
