Emerging Corynebacterium glutamicum systems biology.
Corynebacterium glutamicum is widely used for the biotechnological production of amino acids. Amino acid producing strains have been improved classically by mutagenesis and screening as well as in a rational manner using recombinant DNA technology. Metabolic flux analysis may be viewed as the first systems approach to C. glutamicum physiology since it combines isotope labeling data with metabol...
متن کاملStructural and functional analysis of pyruvate kinase from Corynebacterium glutamicum.
Pyruvate kinase activity is an important element in the flux control of the intermediate metabolism. The purified enzyme from Corynebacterium glutamicum demonstrated a marked sigmoidal dependence of the initial rate on the phosphoenolpyruvate concentration. In the presence of the negative allosteric effector ATP, the phosphoenolpyruvate concentration at the half-maximum rate (S0.5) increased fr...
متن کاملPyruvate carboxylase from Corynebacterium glutamicum: characterization, expression and inactivation of the pyc gene.
In addition to phosphoenolpyruvate carboxylase (PEPCx), pyruvate carboxylase (PCx) has recently been found as an anaplerotic enzyme in the amino-acid-producing bacterium Corynebacterium glutamicum. Using oligonucleotides designed according to conserved regions of PCx amino acid sequences from other organisms, a 200 bp fragment central to the C. glutamicum PCx gene (pyc) was amplified from genom...
متن کاملControl of rep gene expression in plasmid pGA1 from Corynebacterium glutamicum.
The cryptic multicopy plasmid pGA1 (4,826 bp) from Corynebacterium glutamicum LP-6 belongs to the fifth group of rolling-circle-replicating plasmids. A determinant, which negatively controls pGA1 replication, was localized in the leader region of the rep gene coding for the initiator of plasmid replication. This region, when cloned into the compatible vector pEC6, was found to cause decrease of...
متن کاملDevelopment of A Novel Gene Expression System for Secretory Production of Heterologous Proteins via the General Secretory (Sec) Pathway in Corynebacterium glutamicum
Background: Corynebacterium glutamicum (C. glutamicum) is a potential host for the secretory production of the heterologous proteins. However, to this date few secretion-type gene expression systems in C. glutamicum have been developed, which limit applications of C. glutamicum in a secretory production of the heterologous proteins.Objectives: In this stu...
