Gene
N/A
Organism
Capsicum annuum (Bell pepper)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Converts zeaxanthin into antheraxanthin and subsequently violaxanthin. Acts also on beta-cryptoxanthin. Involved in the epoxidation of zeaxanthin.

Catalytic activityi

Zeaxanthin + 2 NAD(P)H + 2 O2 = violaxanthin + 2 NAD(P)+ + 2 H2O.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
