A 5.0-kbp genomic EcoRI restriction fragment which complemented a third subclass of polyhydroxyalkanoic acid (PHA)-leaky mutants of A. eutrophus that accumulated PHA at a lower rate than the wild type was cloned from Alcaligenes eutrophus H16. A 687-bp phaPAe gene on this fragment encoded a 24-kDa protein (M(r) = 23,963), which was referred to as the GA24 protein. The GA24 protein was solubiliz...
