TIGRFAMs

TIGRFAMs is a database of protein families designed to support manual and automated genome annotation.[1][2] Each entry includes a multiple sequence alignment and hidden Markov model (HMM) built from the alignment. Sequences that score above the defined cutoffs of a given TIGRFAMs HMM are assigned to that protein family and may be assigned the corresponding annotations.

Like Pfam, TIGRFAMs uses the HMMER package written by Sean Eddy.[3] TIGRFAMs is produced at the J. Craig Venter Institute. It is one of 11 member databases in InterPro. The current version of TIGRFAMs, release 13.0, has over 4200 models.
