Abstract
Regulatory mechanism in PHB [poly-(hydroxybutyrate)] accumulation by cyanobacteria, especially by a thermophilic isolate,
Synechococcus MA19 was reviewed in comparison with a genetically engineered strain. The strain, MA19 accumulates PHB under
nitrogen starved and photoautotrophic conditions (MA19-N). Little PHB synthase activity was detected in crude extracts from the
cells grown in nitrogen sufficient conditions (MA19 N). The activity was detected exclusively in membrane fractions from
MA19 N. The change of the enzyme activity was insensitive to chloramphenicol, which suggests post-translational activation.
In vitro, acetyl phosphate activated PHB synthase in membrane fractions from MA19 N, and the extent of activation depended
on the concentration of acetyl phosphate. Phosphotransacetylase which catalyzes the conversion of acetyl-CoA to acetyl
phosphate was detected in crude extracts from MA19-N but not in those from MA19 N. These results suggested that
intracellular acetyl phosphate
