The genome of the natural genetic engineer Agrobacterium tumefaciens C58.
The 5.67-megabase genome of the plant pathogen Agrobacterium tumefaciens C58 consists of a circular chromosome, a linear chromosome, and two plasmids. Extensive orthology and nucleotide colinearity between the genomes of A. tumefaciens and the plant symbiont Sinorhizobium meliloti suggest a recent evolutionary divergence. Their similarities include metabolic, transport, and regulatory systems t...
متن کاملReexamining the role of the accessory plasmid pAtC58 in the virulence of Agrobacterium tumefaciens strain C58.
Isogenic strains of Agrobacterium tumefaciens carrying pTiC58, pAtC58, or both were constructed and assayed semiquantitatively and quantitatively for virulence and vir gene expression to study the effect of the large 542-kb accessory plasmid, pAtC58, on virulence. Earlier studies indicate that the att (attachment) genes of A. tumefaciens are crucial in the ability of this soil phytopathogen to ...
متن کاملBiochemical characteristics of the novel haloalkane dehalogenase DatA, isolated from the plant pathogen Agrobacterium tumefaciens C58.
We report the biochemical characterization of a novel haloalkane dehalogenase, DatA, isolated from the plant pathogen Agrobacterium tumefaciens C58. DatA possesses a peculiar pair of halide-stabilizing residues, Asn-Tyr, which have not been reported to play this role in other known haloalkane dehalogenases. DatA has a number of other unique characteristics, including substrate-dependent and coo...
متن کاملEvolution of Enzymatic Activities in the Enolase Superfamily: Galactarate Dehydratase III from Agrobacterium tumefaciens C58
The genome of Agrobacterium tumefaciens C58 encodes 12 members of the enolase superfamily (ENS), eight of which are members of the mandelate racemase (MR) subgroup and, therefore, likely to be acid sugar dehydratases. Using a library of 77 acid sugars for high-throughput screening, one protein (UniProt entry A9CG74; locus tag Atu4196) showed activity with both m-galactarate and d-galacturonate....
متن کاملCloning and characterization of a tetracycline resistance determinant present in Agrobacterium tumefaciens C58.
Agrobacterium tumefaciens C58 and its derivatives give rise to spontaneous mutants resistant to tetracycline at a high frequency. We observed that a mutation affecting a tRNA processing function significantly affected the emergence of such mutants, suggesting that C58 contained a positively acting gene conferring resistance to tetracycline. A cosmid clone conferring resistance to tetracycline i...
