Function

[OLA1_ORYSJ] Hydrolyzes ATP, and can also hydrolyze GTP with lower efficiency. Has lower affinity for GTP (Potential). Exhibits GTPase activity (PubMed:19086295). Confers sensitivity to salinity stress by suppressing the anti-oxidation enzymatic activities and increasing lipid peroxidation thus leading to the accumulation of reactive oxygen species (ROS) (PubMed:23550829).[HAMAP-Rule:MF_03167]^{[1] [2]}
