Citrate Cleavage Enzymes from Developing Soybean Cotyledons: Incorporation of Citrate Carbon into Fatty Acids 1

AUTOR(ES)

Nelson, Daniel R.

RESUMO

Data are presented which demonstrate a citrate cleavage enzyme in the supernatant of a developing soybean (Glycine max L. Merr., var. Harosoy 63) cotyledon homogenate following a 126,000g spin for 2 hours. Activity of the enzyme was observed directly in the supernatant enzyme preparation and in a desalted supernatant preparation by measuring the formation of acetylhydroxamate. Acetylhydroxamate production was dependent on citrate and coenzyme A. The reaction increased with time, citrate, and coenzyme A concentrations.
