Fasta multiple sequence alignment of Release Factor 1 proteins. Sequences were retrieved from GenBank nr database using PSI-BLAST. The alignment was obtained with ClustalW (v2.0.10), and 60% of the gaps was removed with BMGE (v1.0). The alignment was visually inspected and manually adjusted to accuratly align all functionally characterized domains and sequence motifs.
