H/ACA-like RNAs in G. intestinalis. A. RNAmotif model for searching H/ACA-like RNA motifs: This model is based on the common structure of the first stem-loop of G. intestinalis H/ACA-box snoRNAs identified in this study. B. An H/ACA-like RNA with a possible RNase P target. Structural analysis shows strong complementary binding between an H/ACA-like RNA and the G. intestinalis RNase P RNA.
