Bioplastic

Polyhydroxyalkanoates (PHAs), e.g., po1yhydroxybutyrate (PHB), are synthesized from Acetyl co.A used as precursor, and are used for the synthesis of biodegradable plastics with thermoplastic properties. 

At present, PHAs are produced by bacterial fermentation based on Ralstonia eutropha.

The promoter from which expression is initiated is located within the leader region and generates a single RNA transcript called the pre-crRNA.  In the case of E. coli, the CRISPR is associated with eight cas genes, the products of five of which form a complex called Cascade.
