ETHYLENE PRODUCTION FROM β-ALANINE BY AN ENZYME POWDER

In the investigation of a pathway for ethylene biosynthesis, intermediates arising from the metabolism of β-alanine-2-14C to ethylene by enzyme powders from wax-bean cotyledons were isolated and identified by paper and thin-layer chromatography. Quantitative determinations of the label have provided evidence for the conversion of β-alanine through malonic semialdehyde, β-hydroxypropionic acid, and acrylic acid to ethylene.

ABSTRACT Rat and bovine brain have been incubated with testosterone-4-14C under standard conditions. With use of paper chromatography, the extracted metabolites were noted to fall into less-polar, iso-polar, and more polar fractions. The components of the less-polar fraction were separated by acetylation and thin-layer chromatography and the major end-products identified by recrystallization to constant specific activity or constant 3H/14C ratios. Androst-4-enedione and 5α-dihydrotestosterone were formed consistently under the conditions utilized. Trace amounts of other less-polar metabolites were noted occasionally.
