This paper presents results of blind predictions submitted to the GASPS pro
tein structure prediction experiment. We made predictions using the SAM-T98
method, an iterative hidden Markov model-based method for constructing pro
tein family profiles. The method is purely sequence-based, using no structu
ral information, and yet was able to predict structures as well, as all but
five of the structure-based methods in GASPS. (C) 1999 Wiley Liss, Inc.
