Lanmodulin remains unfolded and fails to interact with lanthanide ions in Escherichia coli cells†
Abstract
We report the conformation of a newly discovered specific lanthanide ion (Ln3+) binding protein, lanmodulin (LanM), and its interaction with Ln3+ in Escherichia coli cells using the in-cell NMR technique. We found that LanM remains unfolded and fails to bind Ln3+ in Escherichia coli cells due to the abundance of phosphate groups.
