The Arabidopsis thaliana gene annotated by the locus tag At3g08860 encodes alanine aminotransferase.

ABSTRACT: The aminotransferase gene family in the model plant Arabidopsis thaliana consists of 44 genes, eight of which are suggested to be alanine aminotransferases. One of the putative alanine aminotransferases genes, At3g08860, was attributed the function of alanine:glyoxylate aminotransferase/β-alanine:pyruvate aminotransferase based on the analysis of gene expression networks and homology to other β-alanine aminotransferases in plants. It was earlier demonstrated that At3g08860 is specifically upregulated in response to osmotic stress, but not other stresses (β-alanine is an osmoprotectant in plants). Furthermore, it was shown that the expression of At3g08860 is highly coordinated with the genes of the uracil degradation pathway leading to the non-proteinogenic amino acid β-alanine. Thes
