Table 1 Definition of the corresponds-to relation

Modification

p _i …modification process

L _i

L _i corresponds to p _i

Binding with prior modification

p _i …binding process,

$L_i^{\left(1\right)}$ …modification and binding site of molecule one,

$L_i^{\left(1\right)}$ corresponds to p _j ,

p _j …modification process

$L_i^{\left(2\right)}$ …binding site of molecule two

$L_i^{\left(2\right)}$ corresponds to p _i

Binding without prior modification

p _i …binding process

$L_i^{\left(1\right)}$ …binding site of molecule one,

$L_i^{\left(1\right)}$ corresponds to p _i ,

$L_i^{\left(2\right)}$ …binding site of molecule two

$L_i^{\left(2\right)}$ corresponds to$L_i^{\left(1\right)}$
