A novel method was introduced to predict protein subcellular locations from
sequences. Using sequence data, this method achieved a prediction accuracy
higher than previous methods based on the amino acid composition. For thre
e subcellular locations in a prokaryotic organism, the overall prediction a
ccuracy reached 89.1%. For eukaryotic proteins, prediction accuracies of 73
.0% and 78.7% mere attained within four and three location categories, resp
ectively. These results demonstrate the applicability of this relative simp
le method and possible improvement of prediction for the protein subcellula
r location. (C) 1999 Federation of European Biochemical Societies.
