Novel polyhydroxyalkanoate copolymers produced in Pseudomonas putida by metagenomic polyhydroxyalkanoate synthases [PDF]
Applied Microbiology and Biotechnology, 2016 Bacterially produced biodegradable polyhydroxyalkanoates (PHAs) with versatile properties can be achieved using different PHA synthases (PhaCs). This work aims to expand the diversity of known PhaCs via functional metagenomics and demonstrates the use of these novel enzymes in PHA production.

Engineering of Chimeric Class II Polyhydroxyalkanoate Synthases [PDF]
Applied and Environmental Microbiology, 2004 ABSTRACT PHA synthase is a key enzyme involved in the biosynthesis of polyhydroxyalkanoates (PHAs). Using a combinatorial genetic strategy to create unique chimeric class II PHA synthases, we have obtained a number of novel chimeras which display improved catalytic properties.

Combination of N149S and D171G mutations inAeromonas caviaepolyhydroxyalkanoate synthase and impact on polyhydroxyalkanoate biosynthesis [PDF]
FEMS Microbiology Letters, 2007 Aeromonas caviae polyhydroxyalkanoate synthase (PhaC(Ac)) is an important biocatalyst for the synthesis of practically useful two-component polyhydroxyalkanoate copolymer, poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate] [P(3HB-co-3HHx)]. In a previous study, two PhaC(Ac) mutants that have a single amino acid substitution of either asparagine 149 ...
