Rapid Isolation of Bacterial Photosynthetic Reaction Centers with an Engineered Poly-Histidine Tag
photosynthetic reaction center poly-histidine tag isolation method (bacterium)
2016/5/23
A very rapid method for isolating bacterial photosynthetic reaction centers (RCs) of high purity and yield is described. A poly-histidine tag is engineered at the C-terminus of the RC M-subunit, allow...

2016/5/20
Singlet-triplet mixing in the initial radical-pair state, P[unk]I[unk], of photosynthetic bacterial reaction centers is due to the hyperfine mechanism at low magnetic fields and both the hyperfine and...
Dislocation-mediated growth of bacterial cell walls
Cell wall growth Biophysics Defects Biological Physics
2012/5/29
Recent experiments have illuminated a remarkable growth mechanism of rod-shaped bacteria: proteins associated with cell wall extension move at constant velocity in circles oriented approximately along...

Physical descriptions of the bacterial nucleoid large scales biological implications Biological Physics
2012/4/27
Recent experimental and theoretical approaches have attempted to quantify the physical organization (compaction and geometry) of the bacterial chromosome with its complement of proteins (the nucleoid)...
Stripe formation in bacterial systems with density-suppressed motility
Stripe formation bacterial systems density-suppressed motility Biological Physics
2012/5/3
Engineered bacteria in which motility is reduced by local cell density generate periodic stripes of high and low density when spotted on agar plates. We study theoretically the origin and mechanism of...
Predicting effects of structural stress in a genome-reduced model bacterial metabolism
Predicting effects structural stress genome-reduced model bacterial metabolism
2012/2/28
We studied in silico effects of structural stress in Mycoplasma pneumoniae, a genome-reduced model bacterial organism, by tracking the damage propagating on its metabolic network after a deleterious p...
Coupling between switching regulation and torque generation in bacterial flagellar motor
Supramolecular assembly switching regulation and torque generation bacterial flagellar motor
2011/8/26
The bacterial flagellar motor plays a crucial role in both bacterial locomotion and chemotaxis. Recent experiments reveal that the switching dynamics of the motor depends on the motor rotation speed, ...
