WebbFor proteins, to identify the protein domain family, use blastp against non-redundant protein sequences (nr): : sequence identity > 25% (for protein domains longer 100 aa), E-value < 1e-4. For nucleotides: sequence identity >= 70% (for the sequence of more than 300 nt), E-value < 1e-6.

WebbIn evolutionary biology, conserved sequences are identical or similar sequences in nucleic acids (DNA and RNA) or proteins across species (orthologous sequences), or within a genome (paralogous sequences), or between donor and receptor taxa (xenologous sequences).Conservation indicates that a sequence has been maintained by natural … WebbHowever, exceptions do exist. A classic example is lysozyme, which shares around 50% sequence identity and 70% sequence similarity with -lactalbumin. The two proteins also share similar folds, but their functions are entirely different: the two key catalytic residues of lysozyme are not conserved in -lactalbumin, and the acidic calcium binding ...
