Cooperative mechanisms in coupled motor proteins transport
Subcellular cargos are transported by enzyme molecules called molecular motors by using the chemical energy from hydrolysis of ATP and performing mechanical work in non-equilibrium. Certain motors tread on cytoskeleton ...
Electrostatic regulation of oxygen binding to the neuronal hemoglobin of Cerebratulus lacteus
The neuronal hemoglobin from Cerebratulus lacteus (CerHb) has an O2 affinity (P50 ≈ 1 muM) similar to mammalian myoglobin (Mb), which are both optimized for oxygen storage and release. Mb has a histidine at the E7 helical ...
