HHsearch alignment for GI: 254780367 and conserved domain: TIGR00765

>TIGR00765 yihY_not_rbn YihY family protein; InterPro: IPR004664 Members of this entry include ribonuclease BN (rbn) from Escherichia coli and homologues from a number of bacteria, including the largely uncharacterised BrkB (Bordetella spp. resist killing by serum B) from Bordetella pertussis. Some members have an additional C-terminal domain. Paralogs from E. coli (yhjD) and Mycobacterium tuberculosis (Rv3335c) are part of a smaller, related subfamily that form their own cluster. Ribonuclease BN is a homodimer in E. coli and does not contain a nucleic acid component. Bacteriophage T4 encodes several tRNAs that require this host ribonuclease for maturation. However, host tRNAs with the normal universal 3 sequence of CCA do not appear to be substrates. The substrate specificity of RNase BN appears to be very narrow and its biological role is uncertain. It is one of five ribonucleases in E. coli for which any of the five can confer viability, with the order of efficacy being RNase T > RNase PH > RNase D > RNase II > RNase BN.; GO: 0004540 ribonuclease activity.
