Key Points

This research aims to understand how different architectural structures of macromolecular crowders influence the function and dynamics of prolyl-tRNA synthetase in E. coli.
In vitro studies using spectroscopy to analyze enzyme behavior.
Molecular dynamics simulations to examine interactions between crowders and the enzyme.
Comparison of linear versus branched crowder effects on enzyme performance.
Linear crowders showed a significant increase in enzyme activity compared to branched crowders.
Molecular dynamics simulations indicated distinct dynamic patterns influenced by crowder architecture.
Spectroscopic analysis revealed variations in enzyme conformations based on the type of crowder present.

Implication

In vitro enzyme studies reveal that linear and branched crowders uniquely affect E. coli function, suggesting altered dynamics.

Abstract

In vitro enzyme studies often neglect the highly crowded nature of the cellular interior. Using spectroscopy and molecular dynamics simulations we investigated how crowders of variable architecture, namely, linear polyethylene...
