A few representative statistical dispersion measures describing the interaction space at hand are also presented in the lower part of Table . It can clearly be seen that the range of interaction energetics (from smallest to largest) in SARS-CoV is about as twice as large as that of 2019-nCoV. In addition, both standard deviation and mean absolute deviation are significantly larger in SARS-CoV compared to 2019-nCoV (by ~87% and ~41%, respectively). Indeed, it can easily be inferred that based on the four noncovalent interactions considered in this work, SARS-CoV is more dependent on specific energetically-favored spatial organizations (i.e., n-SARS-b, n=1-4) for effective binding. In particular, interactions 1 and 4 may be identified as potentially-significant binding factors for SARS-CoV, as their potential magnitudes are larger than those of 2 and 3. 2019-nCoV, on the other hand, exhibits rather balanced dependence on the four considered interactions (though interaction 1 is indeed a bit weaker than its counterparts).
