| Abstract |
We have determined the DNA sequence of a Rhizobium meliloti gene that encodes glutamine synthetase II (GSII). The deduced amino acid sequence was compared to that of Bradyrhizobium japonicum GSII and those of various plant and mammalian glutamine synthetases (GS) in order to evaluate a proposal that the gene for this enzyme was recently transferred from plants to their symbiotic bacteria. There is 83.6% identity between the R. meliloti and B. japonicum proteins. The bacterial GSII proteins average 42.5% identity with the plant GS proteins and 41.8% identity with their mammalian counterparts. The plant proteins average 53.7% identity with the mammalian proteins. Thus, the GS proteins are highly conserved and the divergence of these proteins is proportional to the phylogenetic divergence of the organisms from which the sequences were determined. No transfer of genes across large taxonomic gaps is needed to explain the presence of GSII in these bacteria. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 January 2019.
All research outputs
#7,453,350
of 22,786,087 outputs
Outputs from Journal of Molecular Evolution
#450
of 1,438 outputs
Outputs of similar age
#4,218
of 15,319 outputs
Outputs of similar age from Journal of Molecular Evolution
#3
of 11 outputs
Altmetric has tracked 22,786,087 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,438 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one is in the 29th percentile – i.e., 29% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 15,319 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
