| Abstract |
A moderately thermophilic Gram-negative bacterium isolated from the Polok hot spring, Sikkim, India, was identified as a strain (PL17) of Tepidimonas fonticaldi by 16S rDNA sequencing. T. fonticaldi PL17 produces a Type IIP restriction endonuclease; named TfoI. Restriction mapping, run-off sequencing of TfoI-digests of dsDNA fragments, and end compatibility of TfoI with NdeI confirmed that the enzyme recognizes and cleaves the sequence 5'-T^TAA-3', and is thus an isoschizomer of MseI. The TfoI restriction-modification genes in the T. fonticaldi PL17 genome were identified, and the annotated TfoI protein encodes a protein of 181 amino acid residues that shares 47.2% sequence identity with MseI. The native enzyme was purified using a four-column chromatography protocol, and its functional homogeneity was confirmed by standard quality control tests. The ESI-MS measured molecular weight of purified TfoI (20.696 kDa) is in agreement with that of the calculated monomeric molecular weight of the predicted TfoI protein sequence (20.694 kDa). TfoI exhibits optimal activity in the temperature range of 55-70 °C with Mg(+2) or Co(+2) as cofactor. Similar to its isoschizomers, TfoI can be used as the frequent cutter for genome analysis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 21 March 2017.
All research outputs
#14,927,127
of 22,959,818 outputs
Outputs from Extremophiles
#523
of 800 outputs
Outputs of similar age
#200,036
of 334,650 outputs
Outputs of similar age from Extremophiles
#11
of 16 outputs
Altmetric has tracked 22,959,818 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 800 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 32nd percentile – i.e., 32% 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 334,650 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 37th percentile – i.e., 37% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
