WebEnzymes are protein molecules - long chains of amino acid residues. Remember that sticking out all along those chains are the side groups of the amino acids - the "R" groups that we talked about on the page about protein structure. Active sites, of course, have these "R" groups lining them as well - typically from about 3 to 12 in an active site. WebMay 4, 2024 · 3. Tertiary Structure .

WebA so-called salt bridge is often formed by the interaction of closely located positively and negatively charged side chains. Such bridges are often involved in stabilizing three-dimensional protein structure, especially in proteins from thermophilic organisms (organisms that live at elevated temperatures, up to 80-90 C, or even higher, REF).
