  Oxidation of N-hydroxyguanidine 1 by DbH was studied by HPLC and some oxidation products for 1 could be characterized. The compounds generally observed with iron-containing systems are 4-methoxyphenylurea 11 and 4-methoxyphenylcyanamide 12 (Fig. 2). Oxidation of N-(4-chlorophenyl)-N′-hydroxyguanidin

  The related catalytic regions of the human DNA ligases contain three domains, a DNA binding domain (DBD), a nucleotidyl transferase domain (NTase) and an oligonucleotide/oligosaccharide-fold binding domain (OBD) (Ellenberger and Tomkinson, 2008). Similar to DNA ligase I, the DNA ligase III polypep

  For immobilization of enzymes, natural polymers depict several outstanding features as support. These materials are inert, non-toxic, biodegradable and biocompatible. As well as, they can be treated with different functional groups easily by chemical reactions that occur under gentle conditions in a

  2020-01-23

  

  Elastase belongs to chymotrypsin family of proteases and it is responsible for the breakdown of elastin and other proteins, such as collagen and fibronectin, which are fundamental for the ECM elastic properties (Imokawa and Ishida, 2015). Misregulations of this enzyme are involved in skin ageing pro

  Our data also showed that D2 dopamine receptor was down-regulated in the hippocampus, NAc and striatum of F1-MEP animals, which was only significant in the hippocampus. Both agonists and antagonists of D2 dopamine receptor are able to decrease heroin self-administration (Hemby et al., 1996; Rowlett

  From an industrial perspective, the low turnover numbers and limited substrate scope of α-KG halogenases still represents a significant challenge. However, in light of the fact that currently no chemical processes are available for the selective halogenation of aliphatic carbon centers in complex mo

  Introduction Hydrogen sulfide (H2S) and nitric oxide (NO) are important gasotransmitters in the cardiovascular system and instrumental to the fine control of vascular tone [1] and cellular function [2]. NO is synthesized from l-arginine by calmodulin-dependent endothelial nitric oxide synthase (e

  We can think of two ways in which collagen binding could activate DDR (Figure 8). A single collagen triple helix could interact with both DS domains in the DDR dimer (“composite binding site”) and thereby activate the receptor, similar to the situation exemplified by the growth hormone-growth hormo

  Since both the Ub and ISG15 systems are crucial for the innate immune response, many prokaryotic and viral pathogens have evolved ways to hijack them in order to create a “window-of-opportunity” for efficient replication. Several viral and bacterial proteins have been found to directly target these

  STRING protein interactions were used to highlight enzymes directly associated with DHODH (Fig. 10) (Szklarczyk et al., 2015). The reported protein-protein associations are primarily within the de novo nucleotide synthesis pathways (CAD, carbamoyl phosphate synthetase 1, uridine monophosphate synthe

  Collagen compaction and alignment are generated by cell-mediated contractile forces (Stopak and Harris, 1982). The transmission of actomyosin forces to collagen has been mainly attributed to integrins and the activation of the Rho-ROCK pathway (Clark et al., 2007, Kural and Billiar, 2013, Provenzano

  The significance of the difference in the DDR2 binding specificity towards fibrillar and non-fibrillar collagens is not understood, but may imply differences in biological responses when chondrocytes bind to different collagens in the growth plate. Investigations by Labrador et al. (2001) have shown
