1.3.99.28 | more |
directed evolution is used to change the product of Rhodobacter sphaeroides phytoene desaturase (crtI gene product), a neurosporene-producing enzyme, to lycopene. Two generations of random mutagenesis are performed, from which three positive mutants are isolated and sequenced. Site-directed mutagenesis is used to determine the effect of each amino acid change |
