Molecular characterization of a thermophilic endo-polygalacturonase from Thielavia arenaria XZ7 with high catalytic efficiency and application potential in the food and feed industries.

J. Agric. Food Chem. 62(52) , 12686-94, (2015)

Thermophilic endo-polygalacturonases with high catalytic efficiency are of great interest in the food and feed industries. This study identified an endo-polygalacturonase gene (pg7fn) of glycoside hyd...

Horizontal Gene Transfer of Pectinases from Bacteria Preceded the Diversification of Stick and Leaf Insects.

Sci. Rep. 6 , 26388, (2016)

Genes acquired by horizontal transfer are increasingly being found in animal genomes. Understanding their origin and evolution requires knowledge about the phylogenetic relationships from both source ...

Coordination ability of digalactosamine, and di- and trigalacturonic acids. Potentiometric and spectroscopic studies of Cu(II) complexes.

J. Inorg. Biochem. 57(1) , 1-10, (1995)

Potentiometric and spectroscopic (EPR, CD, and absorption spectra) data obtained for digalactosamine and di- and trigalacturonic acid with Cu(II) have shown that the di-sugar binding is usually less e...
