J Biol Chem
. 1982 Feb;
257(4):2049-55.
PMID: 7035458
We have estimated the insulin-stimulated phosphorylation of ATP-citrate lyase by two methods. Isolated hepatocytes incorporate extracellular 32P into [gamma-35P] ATP and immunoprecipitated ATP-citrate lyase to steady state levels by 1...

J Biol Chem
. 1979 Jan;
254(2):245-8.
PMID: 33166
A hormonally induced change in the covalent phosphorylation state of several enzymes is generally regarded as an important mechanism for hormonal modulation of enzyme activity. We have previously demonstrated that...

J Cell Physiol
. 1978 Nov;
97(2):153-9.
PMID: 701384
Dexamethasone induced proline oxidase in cultured LLC-RK1 cells, an epithelial cell line derived from rabbit kidney. The dexamethasone-mediated increase in enzyme activity was concentration and time dependent. Although the effect...

Kowaloff E, Phang J, Granger A, DOWNING S
Proc Natl Acad Sci U S A
. 1977 Dec;
74(12):5368-71.
PMID: 271958
We found that proline oxidase, the first enzyme of the proline degradative pathway, is inhibited by lactate. The Km of the enzyme for proline increases with increasing concentrations of lactate....

Metabolism
. 1977 Aug;
26(8):893-901.
PMID: 875734
Since adrenal corticosteroids are known to affect amino acid metabolism and gluconeogenesis, we examined the relationship of these hormones to hepatic proline oxidase, the mitochondrial enzyme degrading L-proline. In adrenalectomized...

J Cell Physiol
. 1977 Jun;
91(3):369-76.
PMID: 558989
We sought a cultured cell line with Proline Oxidase activity to study the regulation and physiologic role of the enzyme in mammalian tissues. Among the cell lines tested, only LLC-RK1...

Metabolism
. 1976 Oct;
25(10):1087-94.
PMID: 967014
Through the use of specific radioisotopic assays, the activities of enzymes degrading and synthesizing proline were examined in rat liver and kidney as a function of development. Proline oxidase (PO),...

Ann Clin Lab Sci
. 1975 Jul;
5(4):298-302.
PMID: 1163994
Radioisotopic assays have been developed for the enzymes of proline metabolism. These assays are specific and sensitive enough to measure enzyme activities in cultured cells and biopsy specimens. Measurements of...

PMID: 163285
We developed a radioisotopic assay for proline oxidase in which product deltal-pyrroline-5-carboxylate-14-C is reacted with o-aminobenzaldehyde and the radioactivity trapped as the dihydroquinazolinium compound is recovered by ion-exchange chromatography. The...
