Cross-species analysis traces adaptation of Rubisco towards optimality in a low dimensional landscape

, 2010
Rubisco, probably the most abundant protein in the biosphere, performs an essential part in the process of carbon fixation through photosynthesis thus facilitating life on earth.

Purification and Characterization of a Chloroplast Outer-Envelope-Bound, ATP-Dependent Protein Kinase [PDF]

, 1988
An ATP-dependent protein kinase was partially purified from isolated outer envelope membranes of pea (Pisum sativum L., Progress No. 9) chloroplasts. The purified kinase had a molecular weight of 70 kilodaltons, as determined by sodium dodecyl sulfate ...

Ecotoxicology of Mercerized Cellulose–Treated Tannery Effluents Using Salvinia auriculata (Salviniaceae) as a Bioindicator

Environmental Toxicology, EarlyView.
ABSTRACT Given the growing concern over the environmental impacts of industrial effluents, particularly from tanneries, assessing the ecotoxicological risks associated with these effluents, even after remediation treatments, is crucial. Therefore, we aimed to evaluate the potential effects of exposure to raw and treated tannery effluents with ...

Phosphoenolpyruvate Carboxykinase Assayed at Physiological Concentrations of Metal Ions Has a High Affinity for CO2 [PDF]

, 2002
The effect of Mn2+/Mg2+ concentration on the activity of intact, homogeneous phosphoenolpyruvate carboxykinase (PEPCK) from leaves of the C4 grass, Guinea grass (Panicum maximum), have been investigated.

Biodiversity in mountain soils above the treeline

Biological Reviews, EarlyView.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Structure of the Calvin-Benson-Bassham sedoheptulose-1,7-bisphosphatase from the model microalga Chlamydomonas reinhardtii

eLife
The Calvin-Benson-Bassham cycle (CBBC) performs carbon fixation in photosynthetic organisms. Among the eleven enzymes that participate in the pathway, sedoheptulose-1,7-bisphosphatase (SBPase) is expressed in photo-autotrophs and catalyzes the hydrolysis

Phosphorylation of chloroplast ribulose bisphosphate carboxylase/oxygenase small subunit by an envelope-bound protein kinase in situ [PDF]

, 1983
A new protein kinase of the cAMP independent type was found to be bound to the outer envelope membrane of spinach chloroplasts. While stimulated by Mg2+ and inhibited by ADP, the enzyme showed no response to conventional protein substrates and was ...

X-ray structure of Galdieria Rubisco complexed with one sulfate ion per active site [PDF]

, 2002
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyzes the reactions of carboxylation and oxygenation of ribulose-1,5-bisphosphate. These reactions require that the active site should be closed by a flexible loop (loop 6) of the large ...

Effect of Carbonic Anhydrase on the Activity of Ribulose Bisphosphate Carboxylase

Journal of Experimental Botany, 1980
At concentrations of C02 less than saturating, carbonic anhydrase (EC 4.2.1.1) stimulates the carboxylation of ribulose bisphosphate catalysed by ribulose bisphosphate carboxylase (EC 4.1.1.3.9) in vitro. This is not through any beneficial association of the two enzymes but is a consequence of the increased rate of conversion of HCOj ion to C02, the ...
