2. The Sinorhizobium meliloti nutrient-deprivation-induced tyrosine degradation gene hmgA is controlled by a novel member of the arsR family of regulatory genes

Abstract

Researchers have identified a regulatory gene similar to the arsR family in Sinorhizobium meliloti that regulates the homogentisate dioxygenase (hmgA) gene. The nitR locus also produces a protein similar to ATP-binding phosphonate transport protein and transmembrane efflux proteins.

Abstract

Strain N4 of Sinorhizobium meliloti contains a Tn5luxAB insertion in a gene, identified as hmgA, which is induced by carbon and nitrogen deprivation as well as in the presence of tyrosine. The Tn5luxAB-targeted locus shares significant similarity with the human hmgA gene and the corresponding Aspergillus nidulans gene, encoding the enzyme homogentisate dioxygenase, which is involved in tyrosine degradation. Strain N4 was not capable of using tyrosine as carbon source and producing a melanin-like pigment. In addition, it lacked homogentisate dioxygenase activity and was not affected in stationary-phase survival.

Abstract

Research was conducted to isolate and characterize a collection of 33 Sinorhizobium meliloti 1021 using random Tn5-1063 mutagenesis carrying gene fusions created by C- and/or N-deprivation. A further objective was to determine the role of the Tn5-1063-tagged loci in competition. Results indicate that during N-deprivation, S meliloti induces the expression of genes/operons involved in scavenging N from nitrate, amino acids and nitrite. During C-deprivation, S meliloti induces the expression of genes encoding proteins involved in C-assimilation or transport.
