2020-01-29
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

2020-01-25
The major concern of PDE-5-I use in liver cirrhosis is the potentially harmful effect on systemic blood pressure. Data of clinical studies are conflicting [27], [30], [31], [32], but available patient details suggest that in advanced liver cirrhosis, PDE-5-Is lower systemic blood pressure to a great

In the present study, Asian swamp eel CXCR1a (MaCXCR1a), MaCXCR1b, MaCXCR2, MaCXCR3a, MaCXCR3b, and MaCXCR4 were identified from the Asian swamp eel genome. To explore the features and functions of these CXCRs, we focused on the identification and molecular characterization of MaCXCRs, and Iberin mg

2020-01-25
Initially, studies of GPCRs predominantly assessed the signalling pathways downstream of receptors on the cell surface. There is now an understanding that GPCRs can localize to and signal from various intracellular compartments, such as the nucleus (reviewed in [40]). These intracellular pools of re

Most reported binding data are obtained by performing heterologous competition binding experiments and expressing the results as relative binding affinity (RBA). The constructed binding curves should theoretically be sigmoidal in shape with a Hill slope value of one, for a single ligand binding to

The effect of transformation of the linker Y between the carboxylic hyPerFUsion™ high-fidelity PCR Kit residue and the phenyl moiety of 2b was also investigated, and is illustrated in Table 5. Analogs 2b, 16, and 17, possessing conformationally restricted carboxylic acid residues, tended to show st

The different serotypes (A-G) have unique receptors to which they bind to produce the toxic effect on the nerve cells. (Lance, 2004, Rosetto et al., 2014). Intracellularly, the endopeptidase activity of different serotypes of BoNT target selectively a unique group of proteins, the SNARE gpr120 agoni

Are incretins the only mediators of the anti-hyperglycaemic effects of DPP-4 inhibitors? Even though both GLP-1 and GIP were identified as substrates for DPP-4 early on [17], [19], [20], [22], and DPP-4 inhibition in vivo raises levels of the intact endogenous forms of both of them [43], [44], fr

Ung et al. examined a variety of structural features based upon the location of the DFG-motif and the αC-helix to define the conformational space of the catalytic domain of protein kinases [75]. They reported that the DFG motif can move from its active DFG-Din location to the inactive DFG-Dout locat

The proliferation of CCA cell lines can be stimulated by estrogen and other growth factors (Alvaro et al., 2006; DeMorrow, 2009; Mancino et al., 2009). It has also been reported that estrogen positively modulates cholangiocyte proliferation, which is associated with cholangiopathies found in humans

Conclusions In this paper we describe the recombinant expression and characterization of ParI, a C5-DNA-MTase from P. arcticus 273–4. To our knowledge, this is the first characterization of an orphan C5-DNA-MTase from a psychrophilic bacterium. The C5-DNA-MTase could not be expressed in regular E

2020-01-25
Predictions of enzyme topology for DGAT2 are more difficult since the DGAT2 polypeptide sequences are more diverse across species than those of DGAT1. The length and function of the hydrophilic N-terminus preceding the first hydrophobic segment varies with species – for example, segments in fungi ar

Recent studies have shown that the extracellular regulated protein kinase 1 and 2 (ERK1 and ERK2), commonly referred to collectively as ERK 1/2, are members of the mitogen-activated protein kinase (MAPK) family. This family of kinases transport signals from the surface of the cell to the nucleus, th
