Evolution of C(4) phosphoenolpyruvate carboxykinase in grasses, from genotype to phenotype.

open access: yesMolecular biology and evolution, 2009
C(4) photosynthesis is an adaptation over the classical C(3) pathway that has evolved multiple times independently. These convergences are accompanied by strong variations among the independent C(4) lineages. The decarboxylating enzyme used to release CO(

Isolation of mutants of Escherichia coli lacking NAD- and NADP-linked malic enzyme activities [PDF]

open access: yes, 1975
SummaryWhen Escherichia coli utilizes C4-dicarboxylic acids as sole sources of carbon and energy for growth, phosphoenolpyruvate is synthesized by means of phosphoenolpyruvate carboxykinase or by sequential action of malic enzyme and phosphoenolpyruvate ...

AMP-activated Protein Kinase Activation Increases Phosphorylation of Glycogen Synthase Kinase 3β and Thereby Reduces cAMP-responsive Element Transcriptional Activity and Phosphoenolpyruvate Carboxykinase C Gene Expression in the Liver*

open access: yesJournal of Biological Chemistry, 2008
AMP-activated protein kinase (AMPK) activation reportedly suppresses transcriptional activity of the cAMP-responsive element (CRE) in the phosphoenolpyruvate carboxykinase C (PEPCK-C) promoter and reduces hepatic PEPCK-C expression.

Direct Assay to Evaluate Phosphoenolpyruvate Carboxykinase Activity

open access: yesJournal of the Brazilian Chemical Society, 2019
Phosphoenolpyruvate carboxykinase (PEPCK) is a ubiquitous enzyme found in all known groups of organisms, acting in the reversible conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) in the presence of divalent metal ion, and dependent of adenosine 5’-triphosphate (ATP) or guanosine-5’-triphosphate (GTP).
