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.

A maintenance methyltransferase acts constitutively only on hemimethylated sites to convert them to fully methylated sites. Its existence means that any methylated site is perpetuated after replication.  There is one maintenance methyltransferase (Dnmt1) in mice, and it is essential.
