A study of formate utilization in pigeon liver extract.
It is generally recognized that formate is converted to a compound which is utilized in the synthesis of serine (l-3), purines (4, 5), and labile methyl groups (6-8) in animal tissues. Futhermore, compounds which, in the course of their metabolism, form a lrCl compound”l similar to the one formed from formate likewise serve as precursors in the synthetic reactions mentioned above (cf. (9, 10))....
متن کاملThe tyrosine oxidation system of liver. I. Extracts of rat liver acetone powder.
Many investigators of tyrosine oxidation have used systems in vitro such as slices, minces, and, more recently, homogenates of liver. During our search for a suitable preparation other than liver slices for studying the conversion of phenylalanine to tyrosine, an extract of rat liver acetone powder was tested. Although the phenylalanine to tyrosine conversion was not demonstrated, it was found ...
متن کاملThe regulation of phosphoenolpyruvate synthesis in pigeon liver.
1. The intracellular location and maximal activities of enzymes involved in phosphoenolpyruvate synthesis have been investigated in pigeon liver. Enolase and pyruvate kinase were cytoplasmic, and the activities were 50-60 and 180-210mumoles/min./g. dry wt. at 25 degrees respectively. Phosphoenolpyruvate carboxykinase was present exclusively, and nucleoside diphosphokinase predominantly, in the ...

متن کاملSynthesis of triacetic acid lactone by the pigeon liver fatty acid synthetase complex.
The synthesis of triacetic acid lactone (TAL) is effected by purified soluble pigeon liver fatty acid synthetase. This enzyme system synthesizes TAL from acetyl coenzyme A and malonyl coenzyme A in the absence of TPNH, and synthesizes palmitic acid in the presence of TPNH. The major product of the reaction in the absence of TPNH is TAL, and not free triacetic acid. Presumably triacetic acid, bo...
