GTPaza proteinske sinteze (EC 3.6.5.3, elongacioni faktor (EF), inicijacioni faktor (IF), faktor peptidnog oslobađanja ili terminacije) je enzim sa sistematskim imenom GTP fosfohidrolaza (pomoć pri iRNK translaciji).^[1]^[2]^[3]^[4]^[5] Ovaj enzim katalizuje sledeću hemijsku reakciju

GTP + H₂O

\rightleftharpoons

GDP + fosfat

Ova grupa enzima pripada familiji proteina koji učestvuju u prokariotskoj, kao i u eukariotskoj, proteinskoj sintezi.
