BKT coding sequence fused with Pea transit peptide

This part contains the coding sequence (CDS) of β-carotene ketolase (BKT, EC 1.14.11.B16) of algae (Chlamydomonas reinhardti), which catalyzes the conversion of zeaxanthin to astaxanthin. A Pea transit peptide of RUBISCO small subunit has been fused to BKT and the codon has been optimized for rice (Oryza sativa).


Usage and Biology

　As a strong antioxidant, astaxanthin synthesis, especially, its biosynthesis attracts much interest of scientists. BKT symmetrically introduces two keto groups to two β-ionone rings of zeaxanthin to generate astaxanthin in algae (Figure.1).
　In our reconstructed pathway, the CDS of BKY was codon-optimized for rice. In addition, a Pea transit peptide was fused to the BKY for proper sorting into the plastid.
