Abstract / Bemerkung
The stringent response in Corynebacterium glutamicum was investigated. Sets of rrn-cat fusions were constructed in their native chromosomal position to examine the effects of amino acid starvation in a rel(-) strain and a Delta rel mutant defective in (p)ppGpp metabolism. The expression of the six rm operons in the rel(+) control was stringently regulated and reduced to 79% upon induction of amino acid starvation. The Delta rel mutant displayed a relaxed regulation and was unable to reduce the rrn expression under amino acid depletion conditions. In addition, the Delta rel mutant grew more slowly in minimal medium than a rel(+) control. This growth effect was restored by a plasmid-encoded copy. of rel or, alternatively, by supplementation of the minimal medium with the amino acid mixture casamino acids. In particular, the Delta rel strain of C. glutamicum displayed a requirement For the amino acids histidine and serine.
