The enzyme threonine deaminase, in addition to being controlled by feedback inhibition, is controlled by .

noncompetitive inhibition

Explanation:

Non-competitive inhibition (also known as allosteric inhibition) is a type of enzymatic reaction where an inhibitor binds to the enzyme and thus reduces its enzymatic activity. Non-competitive inhibitors are known to bind with the enzyme at allosteric sites, i.e., at different sites rather than the active site. In consequence, during non-competitive inhibition, the substrate can still bind to the enzyme, although that binding to the inhibitor reduces its catalytic efficiency. Conversely, competitive inhibition is produced when the inhibitor binds to the enzyme at the active site, thereby preventing from binding to the substrate.
