Particulate preparations from potato tubers, extracted in 4 mᴍ 2-m ercaptoethanol, catalyze the 3-hydroxylation of 4-hydroxyphenylpropanoid carboxylic acids, including p-coumaric acid and tyrosine, in the presence of NADH (or NADPH) and FAD (or FMN

1. (1) The synthesis and removal of phenylalanine ammonia-lyase (EC 4.3.1.5) in illuminated discs of potato (Solanum tuberosum cv King Edward) tuber tissue has been investigated by density labelling with deuterium (2H) from deuterium oxide (2H2O) fol

Whereas illumination of mature leaf discs and prolonged illumination of spinach beet seedlings gave rise to co-ordinated increases in PAL and C4H followed later by increases together in p C3H and o -diphenol oxidase, relatively brief illumination of

The linked utilization of glycollate and L-serine has been studied in peroxisomal preparations from leaves of spinach beet (Beta vulgaris L.). The generation of glycine from glycollate was found to be balanced by the production of hydroxypyruvate fro

Adenosine nucleosidase (EC 3.2.2.7), which catalyses the irreversible hydrolysis of adenosine to adenine and ribose, has been isolated and purified about 40-fold from leaves of spinach beet (Beta vulgaris L.). The enzyme appeared to be specific for a

[1-(14)C]glycollate was oxidised to(14)CO2 by peroxisomes isolated from leaves of spinach beet about 3 times as rapidly at 35°C as at 25°C; the rate was further increased with rise in temperature to a maximum at 55°C. These increases are shown to

The rate at which H2O2 becomes available during glycollate oxidation for further oxidation reactions, especially that of glyoxylate to formate and CO2, in peroxisomes from spinach-beet (Beta vulgaris L., var. vulgaris) leaves has been determined by m

1. 1. An enzyme catalysing the methylation of caffeic acid to ferulic acid, using S-adenosyl-l-methionine as methyl donor, has been extracted from leaves of spinach beet and purified 75-fold to obtain a stable prepation. 2. 2. The enzyme showed optim

1. 1. Peroxisomal preparations from leaves of spinach beet catalysed the oxidation of formate and oxalate to CO2. 2. 2. Under aerobic conditions, formate oxidation was stimulated by the addition of glycollate or oxalate and inhibited by catalase inhi
