TIC32 — Daucus carota subsp. sativus

Summary

DCAR_000622, designated DcTIC32 on carrot chromosome 1, encodes an uncharacterized protein of the TIC32 family that contains a short-chain dehydrogenase/reductase (SDR) domain and an NAD(P)-binding domain. The product possesses protochlorophyllide reductase activity and calmodulin-binding capacity, and is associated with redox activity. DcTIC32 is linked to chlorophyll biosynthesis and protein transport, and localises to the chloroplast inner membrane. Related genes in other species connect the family to chloroplast protein import and redox regulation.
