Homotropic allosteric enzymes

WebAllosteric Enzymes Enzymes sometimes act as their own regulators. Such enzymes are known as allosteric enzymes. One such enzyme is aspartate transcarbamoylase (also known as aspartate carbamoyltransferase), abbreviated ATCase. ATCase is a complex of 12 subunits, each subunit composed of six catalytic units (C) and six regulatory units (R).
