Engineering bacterial microcompartments into chloroplasts : towards carboxysomes in C 3 plants
نویسندگان
چکیده
Photosynthesis in C3 plants is limited by features of the carbon-fixing enzyme Rubisco, which exhibits a low turnover rate and can also react with O2, leading to photorespiration. In cyanobacteria, bacterial microcompartments known as carboxysomes improve photosynthetic efficiency by concentrating CO2 near Rubisco. Thus transferring the carbon-concentrating mechanism from cyanobacteria to C3 plants is an attractive approach to improve crop photosynthesis. Here we review recent progress in engineering cyanobacterial β-carboxysomes into plant chloroplasts and in replacing C3 plant Rubisco with cyanobacterial Rubisco.

Bacterial microcompartments (BMCs) are self-assembling organelles that sequester segments of biochemical pathways within a protein shell. Given their functional diversity, BMCs constitute a rich source of metabolic modules for applications in synthetic biology. The carboxysome, the cyanobacterial BMC for CO(2) fixation, has attracted significant attention as a target for installation into chlor...

BACKGROUND Carboxysomes are polyhedral protein microcompartments found in many autotrophic bacteria; they encapsulate the CO(2) fixing enzyme, ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) within a thin protein shell and provide an environment that enhances the catalytic capabilities of the enzyme. Two types of shell protein constituents are common to carboxysomes and related microc...
