Crystal structure of S. cerevisiae mitochondrial GatFABCrystal structure of S. cerevisiae mitochondrial GatFAB
FunctionFunction
[GATA_YEAST] Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in the mitochondria. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln). Required for HMG2-induced ER-remodeling.[1] [2] [GATF_YEAST] Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in the mitochondria. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln). Required for proper protein synthesis within the mitochondrion.[3] [4] [GATB_YEAST] Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in the mitochondria. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln).[5]
