Solution structure and RNA-binding of a minimal ProQ-homolog from Legionella pneumophila (Lpp1663)

Domain architecture of selected ProQ/FinO domain proteins. ProQ/FinO-proteins often carry additional amino- or carboxy-terminal domains or extensions. The core domain comprises ∼100 amino acids and is mainly responsible for RNA-binding. The theoretical pI (isoelectric point) values of the isolated domains as well as for the full-length proteins are indicated. (Ec) Escherichia coli, (Se) Salmonella enterica, (Nm) Neisseria meningitidis, (Lp) Legionella pneumophila.
