LTO1_ARATH | function | Thiol-disulfide oxidoreductase catalyzing disulfide bond formation of chloroplast proteins and involved in redox regulation and photosynthetic electron transport. Required for the assembly of photosystem II (PSII) through the formation of disulfide bond in PSBO, a subunit of the PSII oxygen-evolving complex in the thylakoid lumen. Involved in the formation of disulfide bonds in the lumenal protein FKBP13. In vitro, reduces phylloquinone (vitamin K1) and menaquinone (vitamin K2) to their respective quinol. Cannot reduce phylloquinone epoxide to phylloquinone (PubMed:20626653, PubMed:21781282, PubMed:22209765, PubMed:23689258). Plays an important role in regulating the thylakoid lumen redox (PubMed:25412899). |
A0A1P8B950_ARATH LTO1_ARATH | similarity | Belongs to the VKOR family. |
LTO1_ARATH | tissue specificity | Expressed in cotyledons, rosette leaves, stems, cauline leaves and flowers. |
