Polyhydroxyalkanoate synthase from Bacillus sp. INT005 is composed of PhaC and PhaR

Journal of Bioscience and Bioengineering, 2002
A polyhydroxyalkanoate (PHA) biosynthesis gene locus from Bacillus sp. INT005 strain, which had been isolated from a gas field, was cloned and analyzed at the molecular level. We found that a 3.8-kbp DraI-digested fragment of genomic DNA of Bacillus sp. INT005 conferred PHA-producing ability to Escherichia coli, which was PHA-negative. The DNA fragment

Discovery of a new polyhydroxyalkanoate synthase from limestone soil through metagenomic approach

Journal of Bioscience and Bioengineering, 2016
PHA synthase (PhaC) is the key enzyme in the production of biodegradable plastics known as polyhydroxyalkanoate (PHA). Nevertheless, most of these enzymes are isolated from cultivable bacteria using traditional isolation method. Most of the microorganisms found in nature could not be successfully cultivated due to the lack of knowledge on their growth ...

Polyhydroxyalkanoate production by a novel bacterium Massilia sp. UMI-21 isolated from seaweed, and molecular cloning of its polyhydroxyalkanoate synthase gene

Journal of Bioscience and Bioengineering, 2014
We successfully isolated one microorganism (UMI-21) from Ulva, a green algae that contains starch. The strain UMI-21 can produce polyhydroxyalkanoate (PHA) from starch, maltotriose, or maltose as a sole carbon source. Taxonomic studies and 16S rDNA sequence analysis revealed that strain UMI-21 was phylogenetically related to species of the genus ...

Detection of polyhydroxyalkanoate synthase activity on a polyacrylamide gel

Analytical Biochemistry, 2009
This study presents a method to detect active polyhydroxyalkanoate (PHA) synthase on a polyacrylamide gel that combines the polyhydroxybutyrate (PHB) polymerization reaction with Sudan Black B staining. After separation of the protein samples on a modified sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), the slab gel was submerged ...

Class IV polyhydroxyalkanoate (PHA) synthases and PHA-producing Bacillus

Applied Microbiology and Biotechnology, 2015
This review highlights the recent investigations of class IV polyhydroxyalkanoate (PHA) synthases, the newest classification of PHA synthases. Class IV synthases are prevalent in organisms of the Bacillus genus and are composed of a catalytic subunit PhaC (approximately 40 kDa), which has a PhaC box sequence ([GS]-X-C-X-[GA]-G) at the active site, and ...

NONTEMPLATE-DEPENDENT POLYMERIZATION PROCESSES: Polyhydroxyalkanoate Synthases as a Paradigm

Annual Review of Biochemistry, 2005
▪ Abstract  This review focuses on nontemplate-dependent polymerases that use water-soluble substrates and convert them into water-insoluble polymers that form granules or inclusions within the cell. The initial part of the review summarizes briefly the current knowledge of polymer formation catalyzed by starch and glycogen synthases, polyphosphate ...
