Production and Characterization of Synthetic Carboxysome Shells
33 Spatial segregation of metabolism, such as cellular-localized CO2 fixation in C4 34 plants or in the cyanobacterial carboxysome, enhances the activity of inefficient 35 enzymes by selectively concentrating them with their substrates. The 36 carboxysome and other bacterial microcompartments (BMCs) have drawn 37 particular attention for bioengineering of nanoreactors because they are self38 as...
متن کاملSuperresolution microscopy of the β-carboxysome reveals a homogeneous matrix
Carbon fixation in cyanobacteria makes a major contribution to the global carbon cycle. The cyanobacterial carboxysome is a proteinaceous microcompartment that protects and concentrates the carbon-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) in a paracrystalline lattice, making it possible for these organisms to fix CO2 from the atmosphere. The protein responsible for...
متن کاملAtomic-level models of the bacterial carboxysome shell.
The carboxysome is a bacterial microcompartment that functions as a simple organelle by sequestering enzymes involved in carbon fixation. The carboxysome shell is roughly 800 to 1400 angstroms in diameter and is assembled from several thousand protein subunits. Previous studies have revealed the three-dimensional structures of hexameric carboxysome shell proteins, which self-assemble into molec...

متن کاملIdentification and structural analysis of a novel carboxysome shell protein with implications for metabolite transport.
Bacterial microcompartments (BMCs) are polyhedral bodies, composed entirely of proteins, that function as organelles in bacteria; they promote subcellular processes by encapsulating and co-localizing targeted enzymes with their substrates. The best-characterized BMC is the carboxysome, a central part of the carbon-concentrating mechanism that greatly enhances carbon fixation in cyanobacteria an...
