Dextran | dextran 70 kDa, for dextran, the crowding effect clearly depends on its molecular weight | Ananas comosus | |
additional information | crowders, such as dextran (D70) and polyethylene glycol (P12 and P20), destablize and deactivate native bromelain, absorption spectra in phosphate buffer, overview. PEGs tend to have different effects on different proteins depending upon the chemical nature of proteins, while for dextran, the crowding effect clearly depends on its molecular weight. PEG does not seem to follow the size-dependent crowding effect as in the case of dextran | Ananas comosus | |

additional information | analysis of of macromolecular crowding on stem bromelain, i.e. effects of dextran (D70) and polyethylene glycol (P12 and P20) on native bromelain structure, by combining the results of absorption, circular dichroism, fluorescence and activity studies, detailed overview. The overall effect of the crowders on the enzyme is destabilization and deactivation. Molecular docking simulation of bromelain with PEG and dextran | Ananas comosus |
