Chemosynthetic, Photosynthetic, and Cyanobacterial Ribulose Bisphosphate Carboxylase
1978There are compelling reasons to believe that the initial atmosphere of the earth after its formation about 4.7 × 109 years ago was a reducing one consisting chiefly of methane, ammonia, water, and hydrogen (1). In the last two decades considerable research has been described in which numerous organic precursors of biopolymers have been synthesized ...

Photoregulation of the biosynthesis of ribulose bisphosphate carboxylase
Development, 1984ABSTRACT Chloroplast development in higher plants is light dependent, and is accompanied by the synthesis of chlorophyll and the accumulation of many chloroplast polypeptides. There is a 100-fold greater content of the photosynthetic enzyme, ribulose-l,5-bisphosphate carboxylase-oxygenase, in light-grown seedlings of Pisum sativum than ...

Catalytic Mutants of Ribulose Bisphosphate Carboxylase/Oxygenase
1978Ribulose bisphosphate (RuBP) carboxylase/oxygenase, which may be the most abundant protein in nature, is recognized as the cardinal enzyme catalyzing carbon dioxide fixation yielding energy-rich photosynthate.

Ribulose bisphosphate carboxylase activity in halophilic Archaebacteria
Archives of Microbiology, 1990Among the several strains of halobacteria grown heterotrophically, ribulose bisphosphate carboxylase activity was detected in those which accumulate poly (β-hydroxybutyrate), viz. Haloferax mediterranei, Haloferax volcanii and Halobacterium marismortui. In H.

Ribulose bisphosphate carboxylase/oxygenase from Thiocapsa roseopersicina
Archives of Microbiology, 1979d-Ribulose-1,5-bisphosphate carboxylase/oxygenase has been purified 80-fold from malate-grown Thiocapsa roseopersicina by salting out the enzyme from the high-speed supernatant between 68–95% saturation with respect to (NH4)2SO4, gelfiltration through Sephadex G-100, and DEAE-cellulose chromatography followed by sedimentation into a 14–34% glycerol ...

Carboxysomes and Ribulose Bisphosphate Carboxylase/Oxygenase
1988Publisher Summary This chapter focuses on recent advances made in the knowledge of the occurrence, composition, properties, and possible functions of carboxysomes. It also discusses the rapidly expanding field of research on Ribulose 1, 5-bisphosphate carboxylase/oxygenase (RuBisCO) enzymes.

Mechanism of Action of Ribulose Bisphosphate Carboxylase/Oxygenase
1978RuBP carboxylase-oxygenase appears to catalyze carboxylation and oxygenation by homologous mechanisms. A common binding site exists on the enzyme for the acceptor substrate, RuBP. A mechanism is proposed whereby RuBP is isomerized, and a carbanion is generated at C2.

Ribulose bisphosphate carboxylase in algae: synthesis, enzymology and evolution
Photosynthesis Research, 1990Studies demonstrating differences in chloroplast structure and biochemistry have been used to formulate hypotheses concerning the origin of algal plastids. Genetic and biochemical experiments indicate that significant variation occurs in ribulose-1,5-bisphosphate carboxylase (Rubisco) when supertaxa of eukaryotic algae are compared.

Magnetic Resonance Studies on Ribulose Bisphosphate Carboxylase
1978Experiments have been initiated aimed at elucidating the role of the divalent cation required in the RuBP carboxylase-catalyzed reaction. Metal ion is clearly required for activation of the enzyme. However, there is some question concerning an additional role for metal in the catalytic process.
