Comments
Comment typeDescription
CofactorName=Fe cation; Xref=ChEBI:CHEBI:24875; Evidence={ECO:0000250};
DomainThe histidine box domains may contain the active site and/or be involved in metal ion binding. {ECO:0000250}.
FunctionInvolved in the first desaturation step leading to the formation of hexadeca 7,10,13-trienoic acid, the major functional components of thylakoid membranes. Also indirectly involved in the production of the oxylipin dinor-oxo-phyto-dienoic acid implicated in wound signaling. {ECO:0000269|PubMed:15240892, ECO:0000269|PubMed:15579662}.
MiscellaneousSubstrate specificity shifts from delta-7 to delta- 9 desaturation when the protein is retargeted to the cytoplasm.
PathwayLipid metabolism; oxylipin biosynthesis.
PathwayLipid metabolism; polyunsaturated fatty acid biosynthesis.
SimilarityBelongs to the fatty acid desaturase family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast membrane; Multi-pass membrane protein.
Tissue SpecificityHighly expressed in young leaves. Low expression in roots. {ECO:0000269|PubMed:15579662}.
