Protein

Xanthotoxin 5-hydroxylase CYP82C4

Gene

CYP82C4

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score:

Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Can hydroxylate xanthotoxin (8-methoxypsoralen) to form 5-hydroxyxanthotoxin (5-hydroxy-8-methoxypsoralen) in vivo and in vitro (PubMed:18291319).

Involved in the early iron deficiency response, possibly through an IDE1-like mediated pathway (PubMed:21315474).

Involved in the pathway of sideretin biosynthesis from feruloyl CoA, a redox-active catecholic metabolite exuded by roots in response to iron deficiency in order to facilitate the uptake of iron; this pathway consists in the successive conversion from feruloyl CoA to scopoletin, from scopoletin to fraxetin and from fraxetin to sideretin (PubMed:29581584).

Catalyzes the biosynthesis of sideretin via fraxetin hydroxylation (PubMed:29581584).

<p>The checksum is a form of redundancy check that is calculated from the sequence.
