The structure of the recombinant Escherichia coli protein YbcJ, a representative of a conserved family of bacterial proteins (COG2501), was determined by nuclear magnetic resonance. The fold of YbcJ identified it as a member of the larger family of S4-like RNA binding domains. These domains bind to structured RNA, such as that found in tRNA, rRNA, and a pseudoknot of mRNA. The structure of YbcJ revealed a highly conserved patch of basic residues, comprising amino acids K26, K38, R55, K56, and K59, which likely participate in RNA binding.
