Cloning, sequencing, and overexpression of the Anaerobiospirillum succiniciproducens phosphoenolpyruvate carboxykinase (pckA) gene
Article Abstract:
The phosphoenolpyruvate (PEP) carboxykinase-encoding gene from the anaerobic, CO2-fixing, succinate-producing bacterium Anaerobiospirillum succiniciproducens was cloned, sequenced and expressed in Escherichia coli. The gene encoded a 532-amino acid polypeptide with a molecular mass of 58.7 kDa. The sequence of the A. succiniciproducens PEP carboxykinase was similar to those of all known ATP/ADP-dependent PEP carboxykinases.

Insights into Actinobacillus succinogenes fermentative metabolism in a chemically defined growth medium
Article Abstract:
A defined medium, AM3, is created to expand the experimental opportunities for investigating the fermentative metabolism of succinate-producing Actinobacillus succinogenes. AM3 is a phosphate-buffered medium containing vitamins, minerals, NH4Cl as the main nitrogen source, and glutamate, cysteine, and methionine as required amino acids.

Effect of overexpression of actinobacillus succinogenes phosphoenolpyruvate carboxykinase on succinate production in Escherichia coli
Article Abstract:
Succinate fermentation was investigated in Escherichia coli strains over expressing actinobacillus succinogenes phosphoenolpyruvate carboxykinase (PEPCK). Results showed that PEPCK overexpression increased succinate production 6.5- fold.
