| Abstract |
A gene-encoding a dye-linked D-lactate dehydrogenase (Dye-DLDH) homolog was identified in the genome of the hyperthermophilic archaeon Thermoproteus tenax. The gene was expressed in Escherichia coli and the product was purified to homogeneity. The recombinant protein exhibited highly thermostable Dye-DLDH activity. To date, four types of Dye-DLDH have been identified in hyperthermophilic archaea (in Aeropyrum pernix, Sulfolobus tokodaii, Archaeoglobus fulgidus, and Candidatus Caldiarchaeum subterraneum). The amino acid sequence of T. tenax Dye-DLDH showed the highest similarity (45%) to A. pernix Dye-DLDH, but neither contained a known FAD-binding motif. Nonetheless, both homologs required FAD for enzymatic activity, suggesting that FAD binds loosely to the enzyme and is easily released unlike in other Dye-DLDHs. Our findings indicate that Dye-DLDHs from T. tenax and A. pernix are a novel type of Dye-DLDH characterized by loose binding of FAD. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 13 September 2018.
All research outputs
#20,533,292
of 23,103,436 outputs
Outputs from Extremophiles
#693
of 802 outputs
Outputs of similar age
#293,882
of 337,559 outputs
Outputs of similar age from Extremophiles
#15
of 15 outputs
Altmetric has tracked 23,103,436 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 802 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 1st percentile – i.e., 1% 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 337,559 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
