Pseudomonas sp. MBEL 6-19 PHA synthase 1

This is the coding sequence for a Polyhydroxyalkanoate synthase from Pseudomonas sp. MBEL 6-19. The enzyme takes the monomer (D)-lactyl-CoA and produce the PLA homopolymer. This sequence is codon optimized for Pseudomonas putida and includes four amino acid mutations (E130D/S325T/S477G/Q481K) which were found to increase yields of PLA. This type II PHA synthase 1 accept short-chain-length hydroxyacyl-CoAs including lactyl-CoA and 3-hydroxybutyryl-CoA as substrates and support the synthesis of P(3HB-co-LA). We tested different PhaC from different organism to compare the difference of expression.
