RCS3 — Cucumis sativus

Summary

CSA_2G012660 (symbol RCS3) on cucumber chromosome 2 encodes a cysteine synthase family protein with pyrazolylalanine synthase, L-mimosine synthase, beta-pyrazolylalanine synthase, L-3-cyanoalanine synthase, and cysteine synthase activities (EC 2.5.1.47). The gene is associated with downregulation of photosynthesis, regulation of photosynthesis, nitrate metabolism, fruit ripening, fruit development, spore germination, seed germination, the glyoxylate cycle, the TCA cycle, double fertilization, protein breakdown, lipid metabolism, carbohydrate metabolism, homeostasis, response to salt, and NO storage. It localizes to the chloroplast stroma and cytoplasm and is linked to cysteine biosynthesis and amino acid metabolism pathways. Associations with chlorophyll content and oxidative stress response have also been noted. Studies of related genes in other species connect the family to additional synthase activities (EC 2.5.1.52, 4.2.1.50, 2.5.1.51).
