Analysis of two polyhydroxyalkanoate synthases in Bradyrhizobium japonicum USDA 110.
Bradyrhizobium japonicum USDA 110 has five polyhydroxyalkanoate (PHA) synthases (PhaC) annotated in its genome: bll4360 (phaC1), bll6073 (phaC2), blr3732 (phaC3), blr2885 (phaC4), and bll4548 (phaC5). All these proteins possess the catalytic triad and conserved amino acid residues of polyester synthases and are distributed into four different PhaC classes. We obtained mutants in each of these p...
متن کاملNontemplate-dependent polymerization processes: polyhydroxyalkanoate synthases as a paradigm.
This review focuses on nontemplate-dependent polymerases that use water-soluble substrates and convert them into water-insoluble polymers that form granules or inclusions within the cell. The initial part of the review summarizes briefly the current knowledge of polymer formation catalyzed by starch and glycogen synthases, polyphosphate kinase (a polymerase), cyanophycin synthetases, and rubber...

متن کاملClass I and III polyhydroxyalkanoate synthases from Ralstonia eutropha and Allochromatium vinosum: characterization and substrate specificity studies.
Class I and III polyhydroxyalkanoate (PHA) synthases catalyze the conversion of beta-hydroxybutyryl coenzyme A (HBCoA) to polyhydroxybutyrate. The Class I PHA synthase from Ralstonia eutropha has been purified by numerous labs with reported specific activities that vary between 1 and 160 U/mg. An N-terminal (His)6-PHA synthase was constructed and purified with specific activity of 40 U/mg. The ...
متن کاملEngineering Chimeric Antigen Receptors
Chimeric antigen receptors (CARs) are recombinant protein molecules that redirect cytotoxic lymphocytes toward malignant and other target cells. The high feasibility of manufacturing CAR-modified lymphocytes for the therapy of cancer has spurred the development and optimization of new CAR T cells directed against a broad range of target antigens. In this review, we describe the main structural ...
