The first decade of genome sequencing stimulated an explosion in the characterization of unknown proteins. More recently, the pace of functional discovery has slowed, leaving around 20% of the protein
Transmembrane(Tm) and ribosomal (Rp) proteins in Tetrahemna Mt genomes. The amino acid replacement frequencies and patterns in two classifications based on charge (classification 1), and polarity and
Residues are grouped into families following their properties, to consider conservation: hydrophobic are I, L, V, A, F, Y, M; hydrophilic are S and N; negatively and positively charged are E, D and R,
