Not exactly, what I had in mind. The whole point of the consensus
sequence is that here is a sequence that is "in common" to a family of
similar proteins. Any critical residues for activity and folding
should be accounted for in the consensus sequence. But are they?
We'll never know unless someone tries the experiment.
The random mutations would have to be numerous and to get the same
level of information as I tried to explain above. On the other hand,
perhaps mutations as directed by the consensus sequence could be

Tried to send you a reply but the message bounced.
