The PEP—pyruvate—oxaloacetate node as the switch point for carbon flux distribution in bacteria: We dedicate this paper to Rudolf K. Thauer, Director of the Max-Planck-Institute for Terrestrial Microbiology in Marburg, Germany, on the occasion of his 65th birthday [PDF]

, 2017
In many organisms, metabolite interconversion at the phosphoenolpyruvate (PEP)-pyruvate-oxaloacetate node involves a structurally entangled set of reactions that interconnects the major pathways of carbon metabolism and thus, is responsible for the ...

Phosphoenolpyruvate Carboxykinase and Glucose-6-phosphatase Are Required for Steroidogenesis in Testicular Leydig Cells*

Journal of Biological Chemistry, 2012
Background: PEPCK is expressed in Leydig cells of testes, but its role has not been studied. Results: Knockdown and inhibition of PEPCK and Glc-6-Pase inhibited steroidogenesis via activation of AMPK.

Characteristics of C-4 photosynthesis in stems and petioles of C-3 flowering plants [PDF]

, 2002
Most plants are known as C-3 plants because the first product of photosynthetic CO2 fixation is a three-carbon compound. C-4 plants, which use an alternative pathway in which the first product is a four-carbon compound, have evolved independently many ...

Phosphoenolpyruvate carboxykinase in cherry (Prunus avium L.) fruit during development.

Journal of Experimental Botany, 2011
In this study the abundance and location of phosphoenolpyruvate carboxykinase (PEPCK) was determined in the flesh and skin of the sweet cherry (Prunus avium L.) cultivar Durone Nero II during development. PEPCK was not present in young fruit but appeared

-Glutamine supplementation promotes an improved energetic balance in Walker-256 tumor–bearing rats

Tumor Biology, 2017
We evaluated the effects of supplementation with oral l -glutamine in Walker-256 tumor–bearing rats. A total of 32 male Wistar rats aged 54 days were randomly divided into four groups: rats without Walker-256 tumor, that is, control rats (C group ...

Transcriptomic response in Acropora muricata under acute temperature stress follows preconditioned seasonal temperature fluctuations

BMC Research Notes, 2018
Objective Global climate change has resulted in the decline of health and condition of various coral reefs worldwide. Here, we describe expression profiles of Acropora muricata collected during opposing seasons in Otsuki, Kochi, Japan to define the ...

The Role of Tyrosine 207 in the Reaction Catalyzed by Saccharomyces cerevisiae phosphoenolpyruvate carboxykinase

Biological Research, 2010
The functional signifcance of tyrosine 207 of Saccharomyces cerevisiae phosphoenolpyruvate carboxykinase was explored by examining the kinetic properties of the Tyr207Leu mutant. The variant enzyme retained the structural characteristics of the wild-type

Metabolic characterisation of E. coli citrate synthase and phosphoenolpyruvate carboxylase mutants in aerobic cultures [PDF]

, 2006
E. coli is still one of the most commonly used hosts for protein production. However, when it is grown with excess glucose, acetate accumulation occurs.

Comprehensive Detection of Genes Causing a Phenotype using Phenotype Sequencing and Pathway Analysis

, 2013
Discovering all the genetic causes of a phenotype is an important goal in functional genomics. In this paper we combine an experimental design for multiple independent detections of the genetic causes of a phenotype, with a high-throughput sequencing ...
