  Ubiquitination and deubiquitination pathways Ubiquitination is a part of the post-translational modification (PTM) process. Ubiquitination affects proteins in various ways, but its main functions are to signal protein degradation via the 26S proteasome, modify cellular location of proteins, affec

  — 1(2)-Dehydrogenation by a Δ1-KSTD is also a crucial step during Spironolactone degradation of the steroid core. Several Δ1-KSTDs were shown to be active under either aerobic or anaerobic conditions [27,29,47,50,66]. Furthermore, the last common intermediate of both aerobic and anaerobic steroid d

  2021-03-01

  

  An even more striking difference is observed when comparing active site residues, which are evolutionarily very well conserved in other soluble PPases 18, 19. In 31 known PPase sequences, 13 functionally important active site residues are conserved in all sequences, but only two of them (D70 and D97

  Cytochromes P450 (CYP 450) are a superfamily of hemoproteins containing a heme cofactor, which are widely distributed in animals, plants and microbes (Hannemann et al., 2007). CYP450 exhibits a variety of biological functions including biotransformation of drugs, detoxification of endogenous and xen

  Exogenous administration of POCs could theoretically inhibit breastfeeding [69]; however, the evidence in this review does not generally support a negative impact on breastfeeding outcomes. Studies examining the Gap19 of POCs among postpartum women overall demonstrated no adverse effects on measures

  2021-03-01

  

  In humans, the ERα is encoded by the gene ESR1, located on chromosome 6, locus 6q25.1 (Gosden, Middleton, & Rout, 1986). In addition to the full-length ERα isoform (66kDa), several shorter isoforms (36kDa, 46kDa) have been identified as a result of the presence of alternate start codons, or as produ

  2021-03-01

  

  Plasminogen is composed of five N-terminal kringle domains and a C-terminal serine protease domain. The kringle domains have an affinity to lysine and binding of plasminogen with its receptors is dependent on its lysine interacting kringle domains [10], [28]. In the current report, we show that enol

  The estrogen receptor(ER)-dependent signaling pathway plays an important role in bone metabolism by restoring the balance between osteoblastic bone formation and osteoclastic bone resorption [21]. ER has two major isoforms, ERalpha (ER-α) and ERbeta (ER-β), which mediate the effect of estrogen and o

  Another example of negative regulation is the inhibition of the yeast endosome-associated DUB Doa4 by Rfu1 (free ubiquitin chains 1). In a yeast genetics screen, deletion of Rfu1 was serendipitously found to alter global ubiquitin levels [69]. DUBs can regulate these levels by liberating conjugated

  Results To understand how Rad53 functions to maintain replisome integrity, we first analyzed newly synthesized leading- and lagging-strand DNA in wild-type (WT) and rad53-1 mutant cells using BrdU-IP-ssSeq, a method that detects synthesis of both leading and lagging strands (Yu et al., 2014).

  Our previous studies have demonstrated that the DDR2 discoidin domain fully contains the binding site(s) for the fibrillar collagens I and II (Leitinger, 2003, Leitinger et al., 2004). The binding site for collagen I was mapped to three spatially adjacent surface loops within the DDR2 discoidin doma

  A further quandary concerning rediscoveries arises in habitats modified and frequented by humans, where rediscovered species may occur through accidental or deliberate introductions (Metcalf et al., 2007) rather than having persisted despite adverse conditions. Confusion regarding origin could evoke
