Biochemical and molecular characterization of the Pseudomonas lemoignei polyhydroxyalkanoate depolymerase system

Dieter Jendrossek、Andrea Frisse、Astrid Behrends 等 7 位作者1995-02-01Journal of Bacteriology

Pseudomonas lemoignei has five different polyhydroxyalkanoate (PHA) depolymerase genes (phaZ1 to phaZ5), which encode the extracellularly localized poly(3-hydroxybutyrate) (PHB) depolymerases C, B, and D, poly(3-hydroxyvalerate) (PHV) depolymerase, and PHB depolymerase A, respectively. Four of the five genes (phaZ1 to…

Mechanism of cellulose synthesis in Agrobacterium tumefaciens

Ann G. Matthysse、D L Thomas、Alan R. White1995-02-01Journal of Bacteriology

Extracts of Agrobacterium tumefaciens incorporated UDP-[14C]glucose into cellulose. When the extracts were fractionated into membrane and soluble components, neither fraction was able to synthesize cellulose. A combination of the membrane and soluble fractions restored the activity found in the original extracts. Extr…

Homotopy-continuation method for stability analysis in the global minimization of the Gibbs free energy

Amy Cha-Tien Sun、Warren D. Seider1995-02-01Fluid Phase Equilibria

A new algorithm to determine phase equilibria at the global minimum of the Gibbs free energy is presented. Using the Newton homotopy-continuation method, when checking for phase stability, multiple stationary points of the tangent-plane-distance function (TPDF) are determined. Subsets of these are selected as estimate…
