GGT1_ARATH-2 GGT1_ARATH | function | Catalyzes the glutamate:glyoxylate (GGT or GGAT), alanine:glyoxylate (AGT), alanine:2-oxoglutarate (AKT) and glutamate:pyruvate (GPT) aminotransferase reactions in peroxisomes. Required for abscisic acid (ABA)- and stress-mediated responses in an H(2)O(2)-dependent manner. Functions as a photorespiratory aminotransferase that modulates amino acid content during photorespiration (GGAT activity); promotes serine, glycine and citrulline metabolism in response to light. |
GGT1_ARATH-2 GGT1_ARATH | pathway | Amino-acid biosynthesis; glycine biosynthesis; glycine from glyoxylate: step 1/1. |
GGT1_ARATH-2 GGT1_ARATH | pathway | Amino-acid degradation; L-alanine degradation via transaminase pathway; pyruvate from L-alanine: step 1/1. |
GGT1_ARATH-2 GGT1_ARATH | pathway | Photosynthesis; C4 acid pathway. |
GGT1_ARATH-2 GGT1_ARATH | similarity | Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family. Alanine aminotransferase subfamily. |
GGT1_ARATH-2 GGT1_ARATH | tissue specificity | Mostly expressed in leaves, and, to a lower extent, in shoots, stems, flowers, seedlings and green siliques. |
