DCD — Pisum sativum

Summary

PSAT4G066200 (symbol DCD, PsDCD) on garden pea chromosome 4LG4 encodes a protein with deoxycytidylate deaminase and ATP synthase OSCP/delta domains, and is annotated with both DCMP deaminase activity and proton-transporting ATP synthase activity. The gene is associated with photosynthetic electron transport in photosystems I and II, proton motive force-driven ATP synthesis, nitrogen fixation, and nodulation. Its product localises to the chloroplast thylakoid membrane, mitochondrial inner membrane, F1-F0 complex, and cytoplasm. Studies of related genes in other species link the family to transpiration rate, stomatal resistance, and drought tolerance.
