LUT2

Gene

LUT2

Protein

Lycopene epsilon cyclase, chloroplastic

Organism

Arabidopsis thaliana

Length

524 amino acids

Function

Involved in carotenoid biosynthesis. Catalyzes the single epsilon-cyclization reaction which converts lycopene to delta-carotene and neurosporene to alpha-zeacarotene (PubMed:8837512, PubMed:11226339). Required for lutein biosynthesis (PubMed:9789087).

Similarity

Belongs to the lycopene cyclase family.

Mass
