While apparent that [His]6-Artemis fractionated over a HAP column is devoid of 5′–3′ exonuclease activity but still retains DNA-PK dependent hairpin-opening activity, we sought to further assess DNA-PK dependent Artemis overhang cleavage activity to ensure all the in vivo, intrinsic enzymatic activi

Here we uncover a highly diverse superfamily of self-replicating MGEs, dubbed pipolins, which are present in three major bacterial phyla, as well as in mitochondria, and encode divergent PolB carrying TPR1 and TPR2 subdomains. Biochemical characterization of a representative enzyme encoded by a pipo

2021-07-26

The crystal structure of the B. subtilis Maf (BSU28050) was published in 2000, and, to date, it represents the only experimental work with a purified Maf protein (Minasov et al., 2000). The structure revealed a structural fold similar to that found in ITPases and YjjX proteins, which are nucleotide

2021-07-23

P4H is a nonheme iron(II) dioxygenase that uses O2 and α-ketoglutarate as co-substrates (Fig. 1A). The three-dimensional structure of mammalian P4H is unknown. We reasoned that an electrophilic analog of α-ketoglutarate could serve as an irreversible inhibitor of the enzyme and, hence, a useful prob

Another significant finding in our study was the demonstration that the axon-protective action associated with CK2 inhibition correlated with preservation of mitochondrial structure and function in 1-NM-PP1 (Fig. 11). Because of the consistent protection conferred by CK2 inhibition during OGD, impr

Methods Results First, we compared Aβ plaque number, Aβ concentration, and neurobehavior functions between naive APP/PS1 and APP/PS1xEP1−/− mice. Significantly lower Aβ burden in APP/PS1xEP1−/− mice was evidenced by fewer plaques in the hippocampal area and a lower concentration of soluble Aβ42

2021-07-23

Quantifying N6-Methyl-dATP synthesis is greatly complicated by the ubiquitous unevenness of soil surfaces and related water films, which introduce a large uncertainty into size (area) and quality of contact between the soil surface and the membrane, the problem being particularly substantial in wel

2021-07-23

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

2021-07-23

In vasculature, NADPH oxidases (NOXs) are the main sources of O2− generation that involve in the transfer of electrons to molecular oxygen. Endothelin-1 [25] and thromboxane A2 [26] were reported to induce eNOS uncoupling via upregulation of NOXs. Additionally, inhibition of p47 phox, a subunit of N

Among our patients with anti-enolase drusen, those with a relatively short duration from the onset of visual symptoms to the first visit tended to have normal structure of photoreceptors with preserved visual function, despite the presence of drusen-related RPE abnormalities (Cases 1-3 and 8). In co

Since the number of peptides hydrolized by PEP is quite large, it is not easy to relate the increase of enzymatic activity with the altered changes of a concrete peptide. However, it is noticeable that imbalances of several natural substrates of PEP [6], such as angiotensins, bradykinin, vasopressin

While we previously demonstrated that TraG is inhibited by specific transglycosylase inhibitors and that enzymatic activity is strongly reduced upon mutation of the potential catalytic core (Arends et al., 2013), the enzymatic mechanism of both domains was not assigned. Here, by mass spectrometry an

At first, cartilage damage in osteoarthritis reflects the loss of proteoglycan and collagen network that increases the swelling of tissues. The incremented expression of DDR2 receptor has also co-related with the depletion of cartilage in surgically induced OA model [8]. Osteoarthritis, a degenerati
