The Bacillus subtilis RNA helicase YxiN is a modular three-domain protein. The first two domains form a conserved helicase core that couples an ATPase activity to an RNA duplex-destabilization activity, while the third domain recognizes a stem-loop of 23S ribosomal RNA with high affinity and specificity. The structure of the second domain, amino-acid residues 207-368, has been solved to 1.95 A resolution, revealing a parallel alphabeta-fold. The crystallographic asymmetric unit contains two prot ...[more]
