Translational Defects in a Mutant Deficient in YajL, the Bacterial Homolog of the Parkinsonism-Associated Protein DJ-1

We report here that YajL is associated with ribosomes and interacts with many ribosomal proteins and that a yajL mutant of Escherichia coli displays decreased translation accuracy, as well as increased dissociation of 70S ribosomes into 50S and 30S subunits after oxidative stress.
