    Towards engineering a hybrid carboxysome

    Carboxysomes are bacterial microcompartments, whose structural features enable the encapsulated Rubisco holoenzyme to operate in a high-CO2 environment. Consequently, Rubiscos housed within these compartments pos...

    Identification and characterization of a carboxysomal γ-carbonic anhydrase from the cyanobacterium Nostoc sp. PCC 7120

    Carboxysomes are proteinaceous microcompartments that encapsulate carbonic anhydrase (CA) and ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco); carboxysomes, therefore, catalyze reversible HCO3 ...

    The Effects of Antisense Suppression of δ Subunit of Chloroplast ATP Synthase on the Rates of Chloroplast Electron Transport and CO2 Assimilation in Transgenic Tobacco

    In C3 plants, CO2 assimilation is limited by RuBP regeneration rate at high CO2. RuBP regeneration rate in turn is determined by either the chloroplast electron transport capacity to generate NADPH and ATP or the...

    Over-expression of the β-carboxysomal CcmM protein in Synechococcus PCC7942 reveals a tight co-regulation of carboxysomal carbonic anhydrase (CcaA) and M58 content

    Carboxysomes, containing the cell’s complement of RuBisCO surrounded by a specialized protein shell, are a central component of the cyanobacterial CO2-concentrating mechanism. The ratio of two forms of the β-carb...

    The CO2-concentrating mechanism of Synechococcus WH5701 is composed of native and horizontally-acquired components

    The cyanobacterial CO2-concentrating mechanism (CCM) is an effective adaptation that increases the carbon dioxide (CO2) concentration around the primary photosynthetic enzyme Ribulose-1,5-bisphosphate Carboxylase...

    Inorganic carbon transporters of the cyanobacterial CO2 concentrating mechanism

    Cyanobacteria possess an environmental adaptation known as a CO2 concentrating mechanism (CCM) that evolved to improve photosynthetic performance, particularly under CO2-limiting conditions. The CCM functions to ...

    Characterisation of CO2 and HCO3 − uptake in the cyanobacterium Synechocystis sp. PCC6803

    The availability of a complete genome database for the cyanobacterium Synechocystissp. PCC6803 (glucose-tolerant strain) has raised expectations that this organism would become a reference strain for work aimed a...

    Cloning and expression of a prokaryotic sucrose-phosphate synthase gene from the cyanobacterium Synechocystis sp. PCC 6803

    Sucrose is one of several low-molecular-weight compounds that cyanobacteria accumulate in response to osmotic stress and which are believed to act as osmoprotectants. The genome of the cyanobacterium Synechocy...

    Involvement of the cmpABCD Genes in Bicarbonate Transport of the Cyanobacterium Synechococcus sp. Strain PCC 7942

    Cyanobacteria possess a CO2-concentrating mechanism (CCM) which elevates the CO2 concentration around the active site of Rubisco and thereby compensates for the low selectivity of Rubisco for CO2 [1]. Active tran...

    Regulation of CO2 Assimilation Rate by the Chloroplast Cytochrome BF Complex

    The photosynthetic electron transport pathway is responsible for the provision of ATP and NADPH for photosynthetic carbon reduction (PCR) and as such it has the potential to exert strong regulation over photos...

    Reduced levels of cytochrome bf complex in transgenic tobacco leads to marked photochemical reduction of the plastoquinone pool, without significant change in acclimation to irradiance

    Tobacco transgenics with decreased amounts of the FeS apoprotein were generated using an antisense RNA construct targeted against the nuclear-encoded Rieske FeS protein of cytochrome bf complex [Price et al. (...

    Reduced levels of cytochrome b 6/f in transgenic tobacco increases the excitation pressure on Photosystem II without increasing sensitivity to photoinhibition in vivo

    We have examined tobacco transformed with an antisense construct against the Rieske-FeS subunit of the cytochromeb 6 f complex, containing only 15 to 20% of the wild-type level of cytochrome f. The anti-Rieske-Fe...
