GARS Protein, Human (sf9, His)

GARS, a pivotal enzyme, facilitates the ATP-dependent ligation of glycine to the 3'-end of its corresponding tRNA through the formation of an aminoacyl-adenylate intermediate (Gly-AMP). This process is crucial for protein synthesis and maintaining the fidelity of the genetic code. Additionally, GARS exhibits a unique capability to generate diadenosine tetraphosphate (Ap4A), a universal signaling molecule involved in diverse cell regulation pathways, by directly condensing two ATP molecules. This dual enzymatic activity underscores the multifaceted role of GARS in both fundamental cellular processes, such as protein synthesis, and the modulation of signaling cascades through Ap4A, suggesting its potential significance in Ap4A homeostasis. GARS Protein, Human (sf9, His) is the recombinant human-derived GARS protein, expressed by Sf9 insect cells , with N-His labeled tag. The total length of GARS Protein, Human (sf9, His) is 739 a.a., with molecular weight of ~85.5 kDa.
