PAT — Cucumis melo

Summary

MELO3C023373.2 (symbol PAT, also known as CmPAT, VAS1, CmISS1, ISS1, CmVAS1) on melon chromosome 2 encodes a pyridoxal phosphate-dependent aminotransferase belonging to the AspAT/PAT-like family, with activities including methionine-oxo-acid transaminase, L-glutamate:prephenate transaminase, L-aspartate:prephenate transaminase, L-aspartate:2-oxoglutarate transaminase, and 1-aminocyclopropane-1-carboxylate synthase. The gene is associated with auxin and ethylene biosynthesis, inhibition of IAA biosynthetic process, negative regulation of ethylene biosynthetic process, methionine metabolism, L-phenylalanine anabolism, lipogenesis, glutathione metabolism, shade avoidance, fruit ripening, and reverse cholesterol transport. It is linked to IAA content and chilling stress response, and through related genes in other species to harvest index, cytoplasmic male sterility, amino acid content, and sugar content. The protein localises to mitochondria, cytosol, and cytoplasm.
