Rhizobium etli asparaginase II
Bacterial L-asparaginase has been a universal component of therapies for childhood acute lymphoblastic leukemia since the 1970s. Two principal enzymes derived from Escherichia coli and Erwinia chrysanthemi are the only options clinically approved to date. We recently reported a study of recombinant L-asparaginase (AnsA) from Rhizobium etli and described an increasing type of AnsA family members...
متن کاملMultiresistance genes of Rhizobium etli CFN42.
Multidrug efflux pumps of bacteria are involved in the resistance to various antibiotics and toxic compounds. In Rhizobium etli, a mutualistic symbiont of Phaseolus vulgaris (bean), genes resembling multidrug efflux pump genes were identified and designated rmrA and rmrB. rmrA was obtained after the screening of transposon-generated fusions that are inducible by bean-root released flavonoids. T...
متن کاملFermentative and aerobic metabolism in Rhizobium etli.
Strains of Rhizobium etli, Rhizobium meliloti, and Rhizobium tropici decreased their capacity to grow after successive subcultures in minimal medium, with a pattern characteristic for each species. During the growth of R. etli CE 3 in minimal medium (MM), a fermentation-like response was apparent: the O2 content was reduced and, simultaneously, organic acids and amino acids were excreted and po...
متن کاملCloning of the rpoD analog from Rhizobium etli: sigA of R. etli is growth phase regulated.
Rhizobium bacteria fix atmospheric nitrogen during symbiosis with legume plants only after bacterial division is arrested. The role of the major vegetative sigma factor, SigA, utilized by Rhizobium bacteria during symbiosis is unknown. By using PCR technology, a portion of the sigA gene corresponding to domain II was directly amplified from Rhizobium etli total DNA by using two primers designed...
متن کاملNucleotide sequence of the Rhizobium etli nodS gene.
The complete nucleotide sequence of the nodS gene from the bean-nodulating Rhizobium etli, presumably encoding a methyltransferase, was determined. A phylogenetic analysis of five different NodS proteins from three genera of Gram- soil bacteria, Azorhizobium, Bradyrhizobium and Rhizobium, was performed.
