a
The names of the atoms used in this analysis defined in Figure 2 are shown in bold and are followed by conventional names of these atoms (in parentheses).
b
For each included atom i the value of rBfAvr = rBf = Bfatom/<Bfstructure>, represents average over all structures of l‐asparaginases included here, followed by associated value of a standard deviation (± rBfStdDev) and number of independent active sites used in calculations (in parenthesis).
