Regioselectivity in the oxidative deamination of 2-methyl-1,4-diaminobutane catalyzed by diamine oxidases

, 1982
Diamine oxidase from pea seedlings (PDAO) catalyzes the oxidation of 2-methyl-1,4-diaminobutane in a regioselective fashion, whereas diamine oxidase from pig kidney (KDAO) shows no regioselectivity for the same ...

Modified high-performance liquid chromatographic determination of diamine oxidase activity in plasma

, 1990
A previous high-performance liquid chromatographic determination of diamine oxidase activity suitable for tissue homogenates was modified in order to adapt it to plasma samples. Simple additional steps were introduced after the enzyme reaction and before

Mechanistic studies on diamine oxidase: oxidation of α,ω-diamines does not involve an enamine intermediate

, 1994
Three β,β,β′,β′-2H4-labelled α,ω-diamines were synthesized and incubated with pea seedling diamine oxidase. The aminoaldehydes formed by oxidative deamination cyclized to the corresponding imines, which were trapped with benzoylacetic acid. In all three

Glaesserella parasuis infection disrupts the gut–lung axis via microbiota dysbiosis and metabolic reprogramming leading to intestinal barrier impairment in piglets

Frontiers in Cellular and Infection Microbiology
BackgroundGlaesserella parasuis (G. parasuis), is a key respiratory pathogen responsible for Glässer's disease in pigs, characterized by polyserositis, arthritis, and pulmonary lesions.
