A - Alanine (1 letter) Activation of enzymes through ligand binding: why would this be useful? - The binding of a ligand to an allosteric site of a multimeric enzyme often induces positive cooperativity, that is the binding of one substrate induces a favorable conformation change and increases the enzyme's likelihood to bind to a second substrate. Ala - Alanine (3 letter) Arg - Arginine (3 letter) Asn - Asparagine (3 letter) Asp - Aspartic Acid (3 letter) Barr body and relation to heter...
