As an outsider to this field, it would seem another way to approach it would be to ask, of the currently known folds, how many have only one member (excluding evolutionarily related protein families)? If a large number of folds have only been sampled once, it is likely that there are others that

Concerning the number of proteins folds in existence vs. the number of folds already identified: Ed Berry had some good points regarding sample statistics, and I assume the mathematics of that sort of thing is formalized somewhere. The number of examples per protein fold will be skewed by the comm
