Fluxomics of the eastern oyster for environmental stress studies.

Metabolites

Tikunov AP, Stoskopf MK, Macdonald JM.
PMID: 24958387
Metabolites. 2014 Jan 07;4(1):53-70. doi: 10.3390/metabo4010053.

The metabolism of 2-13C/15N-glycine and U-13C-glucose was determined in four tissue blocks (adductor muscle, stomach and digestive gland, mantle, and gills) of the Eastern oyster (Crassostrea virginica) using proton (1H) and carbon-13 (13C) nuclear magnetic resonance (NMR) spectroscopy. The...

Differential Accumulation of Biotin Enzymes during Carrot Somatic Embryogenesis.

Plant physiology

Wurtele ES, Nikolau BJ.
PMID: 16669096
Plant Physiol. 1992 Aug;99(4):1699-703. doi: 10.1104/pp.99.4.1699.

The activities of four biotin enzymes, acetyl-coenzyme A (CoA) carboxylase, 3-methylcrotonyl-CoA carboxylase, pyruvate carboxylase, and propionyl-CoA carboxylase, and the accumulation of six biotin-containing polypeptides were determined during development of somatic embryos of carrot (Daucus carota). Acetyl-CoA carboxylase activity increased...

Influence of Light Intensity on Reductive Pentose Phosphate Cycle Activity during Photoheterotrophic Growth of Rhodospirillum rubrum.

Plant physiology

Porter J, Merrett MJ.
PMID: 16658151
Plant Physiol. 1972 Aug;50(2):252-5. doi: 10.1104/pp.50.2.252.

Light intensity during growth affects the proportion of carbon dioxide fixed by the reductive pentose phosphate cycle relative to that incorporated via C(4) acids in acetate phototrophs of Rhodospirillum rubrum. With cells grown at high light intensity (9000 lux)...

Biochemical aspects of bovine ketosis.

The Biochemical journal

Baird GD, Hibbitt KG, Hunter GD.
PMID: 16742590
Biochem J. 1968 May;107(5):683-9. doi: 10.1042/bj1070683.

1. The concentrations of acetoacetate, beta-hydroxybutyrate and metabolites related to gluconeogenesis were determined in biopsy samples of the livers of ketotic, normal lactating and normal non-lactating cows. Key enzymes of gluconeogenesis in the liver were also assayed. 2. Significant...

Study on roles of anaplerotic pathways in glutamate overproduction of Corynebacterium glutamicum by metabolic flux analysis.

Microbial cell factories

Shirai T, Fujimura K, Furusawa C, Nagahisa K, Shioya S, Shimizu H.
PMID: 17587457
Microb Cell Fact. 2007 Jun 23;6:19. doi: 10.1186/1475-2859-6-19.

BACKGROUND: Corynebacterium glutamicum has several anaplerotic pathways (anaplerosis), which are essential for the productions of amino acids, such as lysine and glutamate. It is still not clear how flux changes in anaplerotic pathways happen when glutamate production is induced...

Analysis of size characterized manganese species from liver extracts using capillary zone electrophoresis coupled to inductively coupled plasma mass spectrometry (CZE-ICP-MS).

Analytica chimica acta

Quintana M, Klouda AD, Gondikas A, Ochsenkühn-Petropoulou M, Michalke B.
PMID: 17723521
Anal Chim Acta. 2006 Jul 28;573:172-80. doi: 10.1016/j.aca.2006.02.045. Epub 2006 Apr 04.

Mn is of toxicological concern because overexposure can lead to progressive, permanent neurodegenerative damage. Monomethyl-Mn-pentadienyl-tricarbonyl (MMT) is used as an anti-knock agent in fuel. Exhausted Mn compounds are absorbed in the lung and transported to the liver. Extended exposure...

Metabolic responses to pyruvate kinase deletion in lysine producing Corynebacterium glutamicum.

Microbial cell factories

Becker J, Klopprogge C, Wittmann C.
PMID: 18339202
Microb Cell Fact. 2008 Mar 13;7:8. doi: 10.1186/1475-2859-7-8.

BACKGROUND: Pyruvate kinase is an important element in flux control of the intermediate metabolism. It catalyzes the irreversible conversion of phosphoenolpyruvate into pyruvate and is under allosteric control. In Corynebacterium glutamicum, this enzyme was regarded as promising target for...

Inhibitors of Pyruvate Carboxylase.

The open enzyme inhibition journal

Zeczycki TN, Maurice MS, Attwood PV.
PMID: 22180764
Open Enzym Inhib J. 2010;3:8-26. doi: 10.2174/1874940201003010008.

This review aims to discuss the varied types of inhibitors of biotin-dependent carboxylases, with an emphasis on the inhibitors of pyruvate carboxylase. Some of these inhibitors are physiologically relevant, in that they provide ways of regulating the cellular activities...

Phosphoenol Pyruvate Carboxylase in Parasitic Plants: Further Characterization in Various Species and Localization at the Level of Cells and Tissues in Lathraea clandestina L.

Journal of plant physiology

Renaudin S, Thalouarn P, Rey L, Vidal J, Larher F.
