Conclusion The past few years have witnessed substantial progress in understanding the structural mechanisms of substrate recognition and the reactions catalyzed by the O-GlcNAc-cycling enzymes, but more work remains. In particular, future research will be needed to establish how OGT and OGA inte

2020-11-25

In mammals, NETs contain DNA and antimicrobial proteins composed mainly of nuclear histones, granule-derived neutrophil elastase, myeloperoxidase, lactoferrin, pentraxin, and gelatinase among others [11], [46], [47], [48]. In fish, NETs-like structures have been observed, and DNA staining and immuno

2020-11-25

The structure of the HOIP RBR–LDD module bound to UbcH5~Ub reveals insights into an activated HOIP component [47]. Contacts between the E2~Ub and the non-cognate RBR module in the crystal suggest how a structure in which the active sites of the E2 and the E3 are in close proximity might look. In thi

BRCC36 is the catalytic subunit responsible for the majority of K63-Ub-specific DUB activity in the cytoplasm and in the nucleus as part of two distinct macromolecular assemblies characterized by the presence of either of the MPN– pseudo DUB proteins KIAA0157 or Abraxas (Cooper et al., 2009, Dong et

2020-11-25

Over the past decade, targeting DNA repair proteins has emerged as an effective tool to enhance chemosensitivity of malignant cells [9]. However, identification and selection of the proper target of DNA repair pathways is critical to increase cytotoxic activity of chemotherapeutic agents in cancer c

In the present work, we ask whether rNMP incorporation is an evolutionarily conserved property of DNA synthesis in Archaea. For this purpose, we used the best characterized hyperthermophilic anaerobe, Pyrococcus abyssi GE5 [47]. This strain duplicates its genome as fast as Bacteria, supported by euk

We next focused our design building into the ribose binding site, which had not been yet utilized in this effort. Compounds bearing a series of five-membered aromatic heterocycles (compound , ) showed reduced inhibition of the Gram-positive isozymes compared with compound , but a 20-fold improved po

A set of small molecule LigI inhibitors were identified through an in silico structure-based screen, using the atomic resolution structure of LigI complexed with nicked DNA [[18], [26]]. This screen yielded inhibitors that were selective for LigI (L82), inhibited both LigI and LigIII (L67) and inhib

In summary, these results are consistent with our hypothesis that chemical nitrosation of BMAA to N-BMAA results in the formation of an alkylating agent. Furthermore, we have shown that N-BMAA is more toxic than BMAA itself. Previously, methylazoxymethanol (MAM), which is also present in the cycad n

Introduction Diacylglycerol kinase (DGK) is a lipid-metabolizing enzyme that phosphorylates diacylglycerol (DG) to produce phosphatidic p-Cresyl sulfate (PA) [[1], [2], [3], [4]]. DG and PA act as lipid second messengers in a wide variety of biological processes. Ten DGK isozymes (α, β, γ, δ, η,

Enzymes involved in microbial steroid degradation are generally not expressed constitutively, but they are upregulated depending on which steroid substrates are present [17,81]. Thus, a cell-free extract prepared from testosterone-adapted C. testosteroni ATCC 11996 cells displayed a 1(2)-dehydroge

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

A third aim of our investigation was to evaluate the impact of the methylation profile of p15, p16, p53, and DAPK, individually or combined, on progression-free and overall survival. We did not find any statistically significant difference in progression-free survival and overall survival in MM case

Trk receptors critically support the development and maintenance of the nervous system, , but their over-expression in various neural and non-neural neoplasms such as breast, pancreatic, lung and neuroendocrine tumors also confers aggressive phenotypes to tumor AZD0156 and correlates with poor pro

On close inspection, the pattern shows large areas of very low point intensity where hardly any trees can be found. Anecdotal knowledge reveals that these regions are covered by a swamp, where the tree species is known to be very unlikely to grow, independent of local soil covariates and topography.
