2020-09-21

Most of the amino PCI-34051 receptor residues contacting the substrate are within the nucleotide-recognition lid (mauve or magenta in Fig. 4A). Two particularly important residues, W69 and Y76, are conserved in eubacteria and in some but not all of eight human AlkB homologs [52], [76] (Fig. 4B). The

2020-09-21

P. falciparum DHFR-TS is a particularly important enzyme, because it is from the protozoan species that is associated with most malaria infections. Since this enzyme is responsible for catalyzing sequential reactions in the thymidylate cycle, its inhibition slows malarial dTMP production and therefo

2020-09-21

Confirmation of the presence of H+-PPase genes in the genomes of the different protists tested was obtained by Southern blot analyses using the PCR-amplified DNA fragments as probes (Fig. 3). In the trypanosomatids L. major and T. cruzi and the euglenoid A. longa, a single band appeared in the filte

In a recent study, Tomkins et al. [7] analyzed the protein-protein interaction network of ROCO proteins. Based on a database analysis, and only taking into account interactions reported in at least two peer-reviewed papers and/or confirmed by two different methods, 113 interactors were revealed for

van Linden et al. developed a comprehensive guide that describes drug and ligand binding to more than 1200 human and mouse protein kinase domains [77]. Their KLIFS (kinase–ligand interaction fingerprint and structure) directory includes an alignment of 85 potential ligand binding-site residues occur

Does hydroxylation of proline have a specific role in the structure and function of the conotoxins? Several studies in the literature provide insights into the role of proline hydroxylation in the Conus peptides. The consequences of proline hydroxylation on oxidative folding and biological activity

The cholinergic system has been shown to play a role in regulation of the inflammatory response [13] as well as in the influence of the metabolism of PCa cells [14]. The reduced activity of cholinesterase (ChoE) and the consequent increased amount of Cladribine has been shown to lead to a cholinergi

An interesting observation pertinent to the immunology of pregnancy comes from a study by Kruse et al., they found that recurrent miscarriage patients with higher serum progesterone levels had lower Th1/Th2 cytokine ratios suggesting that progesterone levels modulate cytokine production patterns. Pr

Binding affinity was measured by a scintillation proximity binding assay using [H]4-OHT (ERRγ) or [H]estradiol (ERα/β) as radioligand. In all cases, the ERβ affinity was not significantly different from ERα. Compounds were compared to , which showed high affinity for both receptors and moderate (six

O-GlcNAc transferase OGT belongs to the metal-independent GT-B superfamily of glycosyltransferases, which has been well-reviewed previously [14,15]. OGT is an essential gene encoded on the X-chromosome, and it has two main regions: a long N-terminal tetratricopeptide repeat (TPR) region and a C-t

Multi-subunit RINGs There are RING-type E3s that exist as multi-subunit assemblies (see Fig. 3B). A striking example is the Cullin RING Ligase (CRL) superfamily [35], which exhibits enormous plasticity in substrate specificity. Each CRL subfamily is characterized by a cullin protein (Cul-1, 2, 3,

One of the most fundamental distinctions between Ub signals is substrate monoubiquitination versus polyubiquitination. With the exception of the E2, UBE2W, which represents a special case because it metaformin only ubiquitinates the flexible N-termini of substrates [5], [6], [20], most examples of m

In general, cellular senescence is considered a programmed response to stress that can be activated by oxidative stress, irradiation or action of substances or drugs. These stressors cause DNA damage and, through the action of specific proteins (p53 and p21), lead to cell senescence (di Fagagna, 200

The presence of external NAD(P)H dehydrogenases (NDE) on the outer surface of the inner mitochondrial membrane enables the mitochondria to oxidize cytosolic NAD(P)H (Moller 2001). A porin (a voltage-dependent anion-selective channel, VDAC) that is abundant in the outer mitochondrial membrane permits
