2021-03-17
The larger eukaryotic ligases, such as LigI and LigIV, also possess an additional N-terminal DNA-binding domain (DBD) that is required for efficient ligation (Fig. 1c) and enables these ligases to encircle DNA [17]. An equivalent helix–hairpin–helix domain is also present in the bacterial NAD-depend

Enzymes repairing alkylated DNA Induction of the Ada regulon Methylated Ada is a strong activator for ada and alkA promoters. Although much weaker than the methylated form, unmethylated Ada acts alone as an activator for ada and alkA promoters. In contrast, the unmethylated protein present in

Sphingosine kinase One of the enzymes closely related to DGKs are the sphingosine kinases (SKs). These enzymes catalyze the conversion of sphingosine (Sph) to sphingosine-1-phosphate (S1P). SKs and DGKs are closely related lipid kinase in term of basic enzymology and the mechanism of regulation a

Widely expressed mammalian adhesion receptors for fibrillar collagens include the α2β1- and α11β1-integrins and the discoidin domain receptors (DDRs), DDR1 and DDR2 (Leitinger, 2011). Integrins and DDRs bind distinct and separate motifs in native fibrillar collagen (Curat et al., 2001, Vogel et al.,

The α3/α4/α5(IV)-chains of mature GBM are built exclusively by podocytes (not by endothelial cells) (Abrahamson et al., 2009), placing the podocytes into the focus of GBM-diseases such as Alport syndrome. Alport syndrome (AS) is caused by mutations in the COL4A3, 4 or 5 genes coding for the α3/α4/α5

The authentic PPase was purified from B. subtilis as described previously [21], whereas the recombinant enzyme was purified to homogeneity from E. coli by a simplified procedure including only phenyl-Sepharose CL-4B column chromatography and DEAE-HPLC [21]. About 26 mg of pure enzyme was obtained fr

It is well known that CysLTs exert potent contractile action on human bronchial smooth muscles through activation of CysLT1 receptors. Indeed, in vitro antigen-induced contraction of passively sensitized human bronchial tissue is markedly suppressed by a pre-treatment with CysLT1 receptor antagonist

Within the BLA, both CRF and the CRF1 receptor have been shown to functionally regulate synaptic activity. In vivo, CRF release into the BLA originates from projections from the CeA (Roozendaal, Brunson, Holloway, McGaugh, & Baram, 2002). Central administration of both CRF and CRF1 agonists has been

LVDP values of ~80% at the end of reperfusion. L-NAME treatment did not modify the contractility detected in ischemic control hearts but annulled the actions of BZ acquiring LVDP values up to 40% (Fig. 4 A). A similar pattern was observed when +dP/dtmax was analysed (Fig. 4 B). LVEDP, as an index o

Other factors also contribute to replication fork progression in DNA damage conditions. For instance, the cullin Rtt101 has a role in fork movement through alkylated DNA, probably associated to a damage tolerance mechanism [52], and TORC signaling is also important for fork progression in response t

The combination of brequinar and 5-fluorouracil (5-FU) has been evaluated to assess whether brequinar-induced uridine depletion would improve 5-FU activity. In cells, 5-FU is metabolized into FdUMP and inhibits thymidylate synthetase, which catalyzes the formation of thymidine monophosphate from deo

Due to cell-cell interactions, high concentrations of LTs can be locally generated in a short period of time during an inflammatory response, thus potentiating LT function. The cellular communication can be mediated between immune cells as well as between immune cells other cell types. Several studi

Pathological changes in animal are powerful indicators of the exposure to environmental stressors. The liver serves as an appropriate organ for the study of pollutant effects because of its high capacity to accumulate pollutant and its susceptibility to histopathological damage by pollutants (Padmin

Phylogenetically three related CXC chemokines are classified as the possible ligands for the teleost CXCR1 and CXCR2. They are referred to as CXCL8_L1 (CXCL8/IL-8/CXCa), CXCL8_L2 (CXCc) and CXCL8_L3 (Alejo and Tafalla, 2011, Chen et al., 2013, Laing et al., 2002, Laing and Secombes, 2004, Nomiyama e
