Figure 2From: Identification of α-type subunits of the Xenopus 20S proteasome and analysis of their changes during the meiotic cell cycleAmino acid sequence comparison of the Xenopus proteasomal α subunits. Matched sequences are boxed. The proteasomal α-type and β-type signatures were detemined by using the 'PROSITE' database [17] and are boxed. The numbers refer to the amino acid position at the end of each line.Back to article page
