Abstract:
ABSTRACT Epoxide hydrolases play an important role in the biodegradation of organic compounds and are potentially useful in enantioselective biocatalysis. An analysis of various genomic databases revealed that about 20% of sequenced organisms contain one or more putative epoxide hydrolase genes. They were found in all domains of life, and many fungi and actinobacteria contain several putative epoxide hydrolase-encoding genes. Multiple sequence alignments of epoxide hydrolases with other known and putative α/β-hydrolase fold enzymes that possess a nucleophilic aspartate revealed that these enzy

Abstract:
In Euphorbia lagascae the major fatty acid in triacylglycerol is the epoxidated fatty acid vernolic acid (cis- 12-epoxyoctadeca-cis-9-enoic acid). The enzymic reactions occurring during the catabolism of epoxidated fatty acids during germination are not known, but it seems likely that the degradation requires the activity of an epoxide hydrolase. Epoxide hydrolases are a group of functionally related enzymes that catalyse the cofactor-independent hydrolysis of epoxides to their corresponding vicinal diols by the addition of a water molecule.

Abstract:
In this study, we investigated the regulatory roles of the juvenile hormone epoxide hydrolase (JHEH) gene in the reproductive process of female Macrobrachium nipponense. Its total cDNA length was 1848 bp, encoding for 460 amino acids. It contained conserved domains typical of epoxide hydrolases, such as the Abhydrolase family domain, the EHN epoxide hydrolase superfamily domain, and the “WWG” and “HGWP” motifs. The qPCR results showed that the expression of Mn-JHEH was the highest in hepatopancreas. Mn-JHEH was expressed at all stages of the embryonic and larval stages. The expression of Mn-JH

Abstract:
The microsomal epoxide hydrolase (mEH) catalyses the hydrolysis of reactive epoxides which are formed by the action of cytochromes P-450 from xenobiotics. In addition it has been suggested that mEH might mediate the transport of bile acids. For the mEH it has been shown that it is co-translationally inserted into the endoplasmic reticulum. Here we demonstrate that the N-terminal 20 amino acid residues of this protein serve as its single membrane anchor signal sequence and that the function of this sequence can also be supplied by a cytochrome P-450 (CYP2B1) anchor signal sequence.

Abstract:
Epoxides and diols of polyunsaturated fatty acids (PUFAs) are bioactive and can influence processes such as tumor cell proliferation and angiogenesis. Studies with inhibitors of the soluble epoxide hydrolase (sEH) in animals overexpressing cytochrome P450 enzymes or following the systemic administration of specific epoxides revealed a markedly increased incidence of tumor metastases. To determine whether PUFA epoxides increased metastases in a model of spontaneous breast cancer, sEH-/- mice were crossed onto the polyoma middle T oncogene (PyMT) background. We found that the deletion of the sEH

Abstract:
Lipoxygenase (LOX)-catalyzed oxidation of the essential fatty acid, linoleate, represents a vital step in construction of the mammalian epidermal permeability barrier. Analysis of epidermal lipids indicates that linoleate is converted to a trihydroxy derivative by hydrolysis of an epoxy-hydroxy precursor. We evaluated different epoxide hydrolase (EH) enzymes in the hydrolysis of skin-relevant fatty acid epoxides and compared the products to those of acid-catalyzed hydrolysis. In the absence of enzyme, exposure to pH 5 or pH 6 at 37°C for 30 min hydrolyzed fatty acid allylic epoxyalcohols to fo

Abstract:
Nineteen potential mimics of 8,9-epoxyeicosatrienoic acid (8,9-EET), a natural bioactive oxylipin, were synthesized and evaluated for their ability to protect renal mesangial cells against sorafenib-induced cell death in a water-soluble tetrazolium (WST-8) assay. All compounds were also evaluated as inhibitors of soluble epoxide hydrolase. As expected of a potent pan-kinase inhibitor the drug sorafenib caused a significant decrease in cell viability in HRMCs. Several analogs containing amide and oxamide groups in place of the epoxide showed efficacy in reducing sorafenib induced human renal me

Abstract:
Type 2 diabetes mellitus (T2DM) can result in microvascular complications such as neuropathy, retinopathy, nephropathy, and cerebral small vessel disease, and contribute to macrovascular complications, such as heart failure, peripheral arterial disease, and large vessel stroke. T2DM also increases the risks of depression and dementia for reasons that remain largely unclear. Perturbations in the cytochrome P450-soluble epoxide hydrolase (CYP-sEH) pathway have been implicated in each of these diabetes complications. Here we review evidence from the clinical and animal literature suggesting the i
