Cloned(Commentary)

Cloned (Comment) Organism
gene ynfE, encoded by the ynfEFGH-dmsD operon, the YnfE protein is synthesized with an N-terminal twin-arginine signal peptide and biosynthesis of the enzyme is coordinated by a signal peptide binding chaperone called DmsD Salmonella enterica subsp. enterica serovar Typhimurium

Protein Variants

Protein Variants Comment Organism
A28Q site-directed mutagenesis, the mutant is devoid of selenate reductase activity and can be rescued by providing chaperon protein DmsD in excess Salmonella enterica subsp. enterica serovar Typhimurium
F35Q site-directed mutagenesis Salmonella enterica subsp. enterica serovar Typhimurium
L24Q site-directed mutagenesis, the mutant is devoid of selenate reductase activity Salmonella enterica subsp. enterica serovar Typhimurium
L33Q site-directed mutagenesis, the mutant is still able to correctly assemble selenate reductase Salmonella enterica subsp. enterica serovar Typhimurium
V31Q site-directed mutagenesis Salmonella enterica subsp. enterica serovar Typhimurium

General Information

General Information Comment Organism
additional information the signal peptide binding chaperone that interacts with the selenate reductase (YnfE) signal peptide is called DmsD and it is encoded within the ynfEFGH-dmsD operon. YnfE signal peptide residues L24 and A28 are important for assembly of an active selenate reductase, and DmsD V16 residue is important for signal peptide recognition and selenate reductase assembly, random mutational analysis. DmsD is a member of the TorD/DmsD/NarJ family of peptide binding proteins. Synthetic peptides containing the YnfE binding epitope can be chemically crosslinked to DmsD and signal peptide binding prevents DmsD dimerization in vitro, interaktion analysis, overview Salmonella enterica subsp. enterica serovar Typhimurium
