proteins with 30% homology should have the same general fold: reference for this ?

Well, you can just do a few sequence comparisons for proteins with
known structure and see if the folds are the same. So it's completely
testable. Though I'd add that this "rule" applies only to proteins in
nature and not to designed proteins (cf. the Parcelus challenge).
