"Codon optimization was used to synthesize the blh gene from the uncultured marine bacterium 66A03 for expression in Escherichia coli. The expressed enzyme cleaved beta-carotene at its central double bond (15,15') to yield two molecules of all-trans-retinal," scientists in Seoul, South Korea report.

"The molecular mass of the native purified enzyme was similar to 64 kDa as a dimer of 32-kDa subunits. The K-m, k(cat), and k(cat)/K-m values for beta-carotene as substrate were 37 mc M, 3.6 min(-1), and 97 mM(-1) min(-1), respectively. The enzyme exhibited the highest activity for beta-carotene, followed by beta-cryptoxanthin, beta-apo-4'-carotenal, alpha-carotene, and...
