Can an 85 kD protein be degraded into a 65 kD protein and a 35 kD protein? I know that with ribosomes the subunit measurements are a sedimentation measurement so the numbers aren't additive, but are kDs like that as well? The question shows an electrophoresis with an 85 kD protein at 10 min turning into a 65 kD protein and a 35 kD protein and I didn't think it could be cleavage into two new peptides because the weights of the two new peptides were too high, but apparently it is.
