Structure-based sequence alignment of Amph-2, Onc, RC-RNase, RC-RNase-61 and RNase A. Elements of secondary structure are shaded (α-helices, magenta; (β-strands, cyan) and labeled below. In the RC-RNase and RNase A sequences, residues shown crystallographically to form the B1 and B2 subsites are white and orange, respectively, while those that form the P1 subsite are encircled. Amph-2 residue numbers are given above the sequences and RNase A residue numbers below. The length of each protein sequence is given at its end. <Q, pyroglutamate. Recent crystallography study on Onc in complex with nucleic acid [33]confirmed Lys9, His10, Lys31 and His97 at the enzyme P1 subsite, Lys33, Thr35, Asp67 and Phe98 at the B1 as well as Thr89 and Glu91 in the B2 subsite.
