| Abstract |
Biomolecule-nanoparticle hybrid bioconjugates based on bioscaffolds such as protein cages and virus capsules have been widely studied. Highly stable and durable biotemplates are a vital pillar in constructing bio-inorganic functional hybrid composites. Here, we introduce a highly heat-resistant coat protein (CP) of Sulfolobus tengchongensis spindle-shaped virus 1 (STSV1) isolated from the hyperthermophilic archaeon as a prospective biological matrix. Our experiments showed that STSV1 CP was successfully cloned and solubly expressed in the Escherichia coli Rosetta-(DE3) host strain. Protein expression was verified by SDS-PAGE and western blot analysis of the reference C-terminally six-histidine (His6) tagged STSV1 CP (HT-CP). Thermal stability experiments showed that the STSV1 coat protein remained fairly stable at 80 °C. The proteins can be purified facilely by heat treatment followed by size exclusion chromatography (SEC). Transmission electron microscopy (TEM) analysis of the purified STSV1 CP protein aggregates demonstrated that the protein could self-assemble into rotavirus-like nanostructures devoid of genetic materials under our experimental conditions. Similar results were obtained for the HT-CP purified by heat treatment followed by Ni-NTA and SEC, indicating that moderately engineered STSV1 CP can retain its self-assembly property. In addition, the STSV1 CP has a high binding affinity for TiO2 nanoparticles. This illustrates that the STSV1 CP can be used as a bioscaffold in nanobiotechnological applications. |

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 09 March 2024.
All research outputs
#7,455,523
of 22,792,160 outputs
Outputs from Extremophiles
#228
of 799 outputs
Outputs of similar age
#73,694
of 228,724 outputs
Outputs of similar age from Extremophiles
#4
of 13 outputs
Altmetric has tracked 22,792,160 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 799 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 42nd percentile – i.e., 42% 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 228,724 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 55% of its contemporaries.
We're also able to compare this research output to 13 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 61% of its contemporaries.
