Identifying deviations from the predictions based on nucleotide composition may identify genes that are under unusual selection pressures, whether for a particular amino-acid composition or for a specific pattern or degree of codon bias.
One model of a ligand-binding pocket in ORs stipulates the existence of 20 variable amino-acid residues on transmembrane helices 3,4 and 5 that constitute the putative ligand 'complementarity-determining region' [ 5, 42].
14%), a typical background for cDNA cloning; 96% of the clusters with detectable homology have nematode homologs (1,227/1,280), 17% have only nematode homology, and in the vast majority of cases, higher conservation is seen to a nematode sequence than any non-nematode sequence; additional confirmation of nematode origin comes from the presence of an SL1 trans -spliced leader sequence on some genes; all sequences with strong amino-acid homology to prokaryotic genes were closely examined and in no cases were the high levels of identity maintained at the nucleotide level (as would be the case with a contaminating sequence).
Orthologous pairs show an average amino-acid identity of 62% and 16S rDNA identity of 89% between E. coli and Buchnera.
For phylogenetic analysis, the fact that some amino acids (such as arginine) change rapidly and predictably with GC content slightly undermines the idea that amino-acid sequences are more stable than nucleotide sequences: pairs of species with convergent GC contents might also evolve convergent protein sequences, especially at functionally unconstrained positions.
