  In addition to providing substantial insight into substrate recognition, structural studies have revealed important details about mechanisms of glycosylation and HCF-1 cleavage [28,30,33]. Activation of the nucleotide-sugar is accomplished through interactions of the β-phosphate with the N-terminus

  These reactions are used to account for variations in protein solubility or vesicle recovery. For example, with DGKθ we have found it necessary to maintain the purified enzyme in a solution of 0.01% DDM (DGK-D dilution buffer) in the control reaction to prevent enzyme loss due to aggregation or adhe

  Effect of a C4-C5 double bond — The presence of a double bond at the substrate’s C4-C5 position affects the reactivity of Δ1-KSTDs to varying extent, depending on the enzyme. Most 3-ketosteroids that are converted by Δ1- KSTDs have this double bond. For some Δ1-KSTDs this double bond is even require

  Introduction The cys-loop ligand gated ion channels (LGICs) are membrane-bound proteins mediating fast transduction from chemical to electrical signals at neuronal synapses and neuromuscular junctions [1], [2]. Each subunit that makes up the pentameric LGIC architecture possesses a dicysteine bri

  Introduction The Discoidin Domain Receptors (DDRs), comprising DDR1 and DDR2, are collagen-binding receptor tyrosine kinases (RTKs) that function as microenvironmental sensors at the interface of the extracellular matrix and the intracellular signal transduction machinery [1]. In response to ligand

  A cocktail approach can detect the activities of multiple CYP 450 isoforms following administration of multiple CYP-specific substrates in a single experiment. Caffeine, losartan, omeprazole, dextromethorphan and midazolam are often used as substrates in “cocktail probes” of human cytochrome CYP1A2,

  This work aimed to investigate whether the increase in liver lipid depots, observed in the fetuses from rats fed a saturated-fat-rich diet, persists later in life in the offspring (a) at 21days of age immediately after weaning and (b) at 140days of age, after healthy nourishing. Furthermore, we want

  The importance of mitochondria as site of aerobic oxidation of metabolic fuels, such as FA, has been recognized for a long time. It has been observed that the number of mitochondria may vary in response to cellular metabolic requirements and hormonal environment (Gao et al., 2014). In order to susta

  2020-09-10

  

  Protein ubiquitination occurs at the lysine residues, and is mediated by the sequential reactions of ubiquitin-activating enzyme (E1), conjugating enzyme (E2), and ligase (E3). The first step in this process comprises the ATP-dependent activation of ubiquitin by E1 to form a ubiquitin–E1 conjugate.

  Introduction Double strand break (DSB) is the most deleterious damage that threats DNA integrity. This frequent damage arises from environmental stress like UV, chemical agents or ionizing radiations (IRs). Although environmental stress does not lead directly to DSB, it produces 6-Bnz-cAMP sodium s
