What is the key structural feature of the enzyme glutamine amidotransferase?
Explanation
Glutamine amidotransferases are a class of enzymes that catalyze the transfer of the amide nitrogen from glutamine to an acceptor molecule. Their characteristic structure involves two separate active sites connected by an internal channel that allows the unstable intermediate, ammonia, to travel directly from the site of its generation to the site of its utilization without being released into the solvent.
