2020-04-26
Mammalian cells contain significant amounts of a relatively lesser known enzyme that shows marked specifity for ether lipids containing AA and other 20–22 carbon fatty acids. This enzyme is called CoA-independent transacylase (CoA-IT), and transfers polyunsaturated moieties of 20–22 carbons, typical

2020-04-26
Molecular characterization of LEI/L-DNase II LEI, like most serpins, is a metastable protein and its anti-protease activity is related to its “stressed to relaxed transition”. So that, the inhibition of elastase by the well described suicide mechanism generates the cleaved form of LEI (see Padron

As suggested by previous data [45], we identified that the N-terminal and C-terminal domains of DDX3 were enriched in intrinsically disordered regions (Fig. 6). We also found that this characteristic was conserved in the external domains of several homologs of DDX3 (from yeast to human) and all desc

Introduction Klebsiella pneumoniae, a Gram-negative enteric bacterium, is an organism with significance in both biomedicine and biotechnology. Some of the strains of K. pneumoniae are opportunistic pathogens, which can cause suppurative infection, pneumoniae and urinary tract infection in humans (B

Further proof is required as to whether ER membrane receptors play a role in the maintenance of bone mass. It is also possible that other non-genomic pathways may be involved. Nevertheless, whatever the precise mechanism of action of estrogens may be, the imbalance between bone formation and resorpt

Several limitations of this study need to be acknowledged. First, although 200 patients were recruited into this study and completed assessments at baseline, only 89 patients completed the cognitive tests after 8weeks of treatment. The relatively long study period (8weeks) was the main reason for t

As the angular structure of compound cannot be differentiated from the linear structure by H NMR spectroscopy, a NOESY NMR experiment was performed to unambiguously characterize the regioselectivity of the final compound. In the linear compound , a signature correlation between the proton of the t

Besides chemopreventive effects against oxidative DNA damage we evaluated the protective effects of the three Hypericum sp. and isolated compounds against alkylating DNA damage induced by MMS in HT29 cells. Human exposure to alkylating agents, from different sources, occurs in a continuous way and i

Materials and methods Results Discussion EP is an important tick borne disease caused by T. equi and B. caballi. Current chemotherapeutic drugs for EP are limited, as only diminazene aceturate and imidazole dipropionate are available. Novel and effective chemotherapeutics for treatment of E

As a basis for the DDR1 substrate identification approach detailed below, we first set out to perform 2D-gel electrophoresis with lysates isolated from collagen-stimulated human breast cancer MDA-MB-231 melatonin receptor agonist overexpressing DDR1 (b-isoform). This allowed us to determine whether

Another enzyme class that has emerged as a potential alternative to P450s are the so-called ‘unspecific peroxygenases’ (UPOs). They also contain a heme but are extracellularly expressed fungal enzymes that are often more stable than P450 monooxygenases. Importantly, UPOs use H2O2 instead of O2 as th

More importantly, Santagata et al. have suggested a new breast cancer subtyping method according to ER, androgen receptor (AR), and VDR with a higher prognostic value than the ordinarily used method based on ER, progesterone receptor (PR) and Her2 (Santagata et al., 2014). This implies that such com

2020-04-26
Enolases are among the most abundantly expressed cytosolic proteins. They are metalloenzymes that catalyze the conversion of 2-phosphoglycerate to phosphoenolpyruvate [18]. Eubacteria and archaebacteria have a single enolase gene (reviewed in [19]). Despite the lack of signal peptides or cognate pro

Some family I DNA ligases can use dATP as nucleotide cofactor. For instance, human Ac-IETD-AFC I uses dATP with a catalytic efficiency that is only 36-fold lower in comparison to ATP [9]. EhDNAlig is unable to use dATP as a nucleotide cofactor, indicating a more constrained active site in compariso

Contrary to genetic aberrations epigenetic methylation markers with broad coverage of OvCa subtypes were detected in primary tumors [21]. Ibanez de Caceres et al. [22] identified hypermethylation of BRCA1, APC, p16, p14, DAPK or RASSF1A in 50 of 50 primary tumors. Moreover the methylation pattern wa
