WebGlutamine synthetase acts like a tiny molecular computer, monitoring the amounts of nitrogen-rich molecules. It watches levels of amino acids like glycine, alanine, histidine and tryptophan, and levels of nucleotides like AMP and CTP. If too much of one of these molecules is made, glutamine synthetase senses this and slows production slightly.
