I don't know whether anyone help you already or not, but one place you
look for answer to these questions are in journal articles, not text
For example, if you do subject keyword search in Medline with words
"aldolase fructose lysine", you get 16 references. One of the
reference is titled: "Lysine-146 of rabbit muscle aldolase is essential
for cleavage and condensation of the C3-C4 bond of fructose
1,6-bis(phosphate).". I will let you figure out the source, which
shouldn't be difficult to identify.
