No, since it is merely a normal and common procedure for a person skilled in the art to isolate the DNA sequence encoding protein X when a partial amino acid sequence of protein X was already known from the prior art. Even if no partial amino acid sequence of protein X has been disclosed in the prior art, but protein X was described in a highly purified form which would make it possible for a skilled person to sequence protein X, the claimed invention would lack inventive step.
