I don't really know how to put this in words but as I am having a protein sequence, I viewed its conserved domains detected using CD Search at NCBI and then I obtained its superfamily with description that this protein contains two copies of motif, say HXXHH, however, I only found one within the sequence. What does this infer? I'm quite of a beginner to this field, so sorry if the question does not make much sense. :(
Please advice. Thank you in advance!
