Structure-based sequence alignments. (a) The Sm protein sequences aligned by the superposition in Fig. 5[link](a). Conserved hydrophobic residues are highlighted in cyan and highly conserved glycines in yellow. Residues important for nucleotide binding are indicated with an asterisk and highlighted in red (Asp or Glu), magenta (mostly aromatic), green (invariant Asn) and blue (Arg or Lys). (b) Sm-site nonanucleotides of human U1, U2, U4 and U5 snRNA. The heptad bound one-to-one by the seven Sm proteins is shown in red.
