Metioninska g-lijaza (EC 4.4.1.11, L-metioninaza, metioninska lijaza, metioninaza, metioninska detiometilaza, L-metionin gama-lijaza, L-metionin metantiol-lijaza (deaminacija)) je enzim sa sistematskim imenom L-metionin metantiol-lijaza (deaminacija, formira 2-oksobutanoat).^[1] Ovaj enzim katalizuje sledeću hemijsku reakciju

L-metionin + H₂O

\rightleftharpoons

metantiol + NH₃ + 2-oksobutanoat (sveukupna reakcija)

(1a) L-metionin $\rightleftharpoons$ metantiol + 2-amoniobut-2-enoat (1b) 2-amoniobut-2-enoat + H₂O $\rightleftharpoons$ 2-oksobutanoat + NH₃ (spontana reakcija)

Ovaj enzim je piridoksal-fosfatni protein.
