초록

An isolated phbC gene from Alcaligenes latus was reintroduced into the parent A. latus through the transformation process, and the effect of the amplified phbC gene on the biosynthesis of P(3-hydroxybutyrate-3-hydroxyvalerate) [P(3HB-3HV)] and P(3-hydroxybutyrate-4-hydroxybutyrate) [P(3HB-4HB)] in the transformant A. latus was investigated. The biosynthesis rate and content of the above copolymers increased up to 1.3-fold after enforcing its own phbC gene, and the molar fractions of 3HV and 4HB in P(3HB-3HV) and P(3HB-4HB) also changed remarkably from 35.0 to 48.0% and from 34.0 to 56.0%, respectively, showing a critical role of PHB synthase which catalyzes the polymerizing reactions between eiher 3HV or 4HB from precursor compounds and 3HB.
