Ribosomal protein L25 is an RNA binding protein, that binds 5S rRNA. This family includes Ctc from B. subtilis Swiss:P14194, which is induced by stress.

1: The NMR structure of Escherichia coli ribosomal protein L25 shows homology to general stress proteins and glutaminyl-tRNA synthetases. Stoldt M, Wohnert J, Gorlach M, Brown LR; EMBO J 1998;17:6377-6384. PMID:9799245

2: The NMR structure of the 5S rRNA E-domain-protein L25 complex shows preformed and induced recognition. Stoldt M, Wohnert J, Ohlenschlager O, Gorlach M, Brown LR; EMBO J 1999;18:6508-6521. PMID:10562563
