Physiology and molecular genetics of poly(β‐hydroxyalkanoic acid) synthesis in Alcaligenes eutrophus

The Alcaligenes eutrophus genes for β‐ketothiolase, NADPH‐dependent acetoacetyl‐CoA reductase and poly(β‐hydroxybutyric acid) synthase (PHB synthase) which comprise the three‐step PHB‐biosynthetic pathway, were cloned and molecular studies revealed that these genes are organized in a single operon.
