How long a main sequence star lives depends on how massive it is. A higher-mass star may have more material, but it burns through it faster due to higher core temperatures caused by greater gravitational forces. While the sun will spend about 10 billion years on the main sequence, a star...

The SARS-CoV-2 WT Mpro gene (UniProtKB P0DTD1; nsp5 sequence) was codon optimized for E. coli and cloned into a SUMOstar vector (LifeSensors Inc.; Malvern, PA, USA) as a C-terminal fusion to an N-terminal small ubiquitin-related modifier (SUMO) tag using BsaI and XhoI (GenScript;...
The most notable difference is that, in BUB1 and CENP-U, there are Ser-Thr-Pro sites at the PLK12 position, whereas a Ser-Thr-X sequence remains at the PLK11 site (not in BUBR1, however). Because proline versus non-proline specificity in the P+1 position of protein kinases are ...
Since the characteristics of a Main-Sequence star are almost constant for long periods of time, we don't need to worry about changes in the brightness altering the results of a comparison such as the one shown in the next figure: Hertzsprung-Russell Diagram Showing Masses and Luminosities of ...
Nevertheless, large amounts of dust have been detected around Pictoris and many other main sequence (MS) stars, according to their IR excess. The study of the evolutionary status, origin and lifetime of such environment is related to scenarii of star and planetary system formation, but it is...
