A mutant Era GTPase suppresses phenotypes caused by loss of highly conserved YbeY protein in Escherichia coli

In this study, we performed whole-genome sequencing of YbeY deletion strains with improved growth characteristics and have characterized a point mutation in the era gene, era(T99I), that encodes an Era protein variant whose threonine residue at position 99 is replaced by an Isoleucine residue.
