Protein
Fibrillin-5, chloroplastic
Organism
Arabidopsis thaliana
Function
Isoform 1: Essential for plastoquinone-9 (PQ-9) biosynthesis (PubMed:26432861, PubMed:29741733). Interacts with the diphosphate synthases SPS1 and SPS2, and binds to the hydrophobic solanesyl moiety, which is generated by SPS1 and SPS2, in FBN5-SPS homodimeric complexes to stimulate the enzyme activity of SPS1 and SPS2 (PubMed:26432861).
Similarity
Belongs to the PAP/fibrillin family.
