In the present study, we propose a continuous assay for the screening of sn-2 lipases by using triacylglycerols (TAGs) from Aleurites fordii seed (tung oil) and a synthetic TAG containing the α-eleostearic acid at the sn-2 position and the oleic acid (OA) at the sn-1 and sn-3 positions [1,3-O-dioleoyl-2-O-α-eleostearoyl-sn-glycerol (sn-OEO)]. Each TAG was coated into a microplate well, and the ...

Comparative studies on the ABC model of floral development have revealed extensive conservation of B and C class genes, but have failed to identify similar conservation for A class genes. Using a reverse genetic approach, we show that the previous inability to obtain Antirrhinum mutants corresponding to the A class gene AP2 of Arabidopsis reflects greater genetic redundancy in Antirrhinum . Ant...

The glyceraldehyde-3-phosphate dehydrogenase (gpd) promoter was used to drive expression of lip2, the gene encoding lignin peroxidase (LiP) isozyme H8, in primary metabolic cultures of Phanerochaete chrysosporium. The expression vector, pUGL, also contained the Schizophyllum commune ura1 gene as a selectable marker. pUGL was used to transform a P. chrysosporium Ura11 auxotroph to prototrophy. U...

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease with an actuarial mortality rate is about 90% (Cheung, 2013), corresponding to the fourth leading cause of cancer death. Worldwide, the incidence of all types of pancreatic cancer (85% of which are PDAC) ranges from 1 to 10 cases per 100, 000 people (Ryan et al., 2014), Accounted for 2% of all malignant tumor incidence in china. A...

Antifungal resistance and virulence properties of Candida albicans are a growing health problem worldwide. To study the expression of virulence and azole resistance genes in 39 clinical strains of C. albicans, we used a model of infection of human vaginal epithelial cells with C. albicans strains isolated from Mexican women with vulvovaginal candidiasis (VVC). The strains were identified by PCR...

The lipase2 from Yarrowia lipolytica (YLLip2) is a yeast lipase exhibiting high homologous to filamentous fungal lipase family. Though its crystal structure has been resolved, its structure-function relationship has rarely been reported. By contrast, there are two amino acid residues (V94 and I100) with significant difference in the substrate binding pocket of YLLip2; they were subjected to sit...

Lipoic acid is an essential cofactor for a variety of mitochondrial enzymes. We have characterised a gene from Saccharomyces cerevisiae which appears to encode a protein involved in the attachment of lipoic acid groups to the pyruvate dehydrogenase and glycine decarboxylase complexes. The predicted protein product of this gene has significant identity to the lipoyl ligase B of both Escherichia ...
