N-terminal nucleophile aminohydrolases (Ntn hydrolases) superfamily models

A superfamily is represented by one or more models; usually there is more than one model representing the superfamily. Since each model is built to capture the whole superfamily, they are likely to be overlapping and sometimes are mostly overlapping or even redundant to each other. Also models often do not score their own seed sequence more highly than other sequences in the superfamily, so it is a mistake to think that the model represents the seed sequence.

All models are available for immediate download after obtaining a license by filling in a short online registration form. Licenses are free for academic and commercial purposes.

Plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be viewed for each model by following the model ID link.
