SignalP - Prediction of signal peptide and cleavage sites in gram+, gram- and eukaryotic amino acid sequences

This Web Service implements SignalP v. 3.1. It predicts the presence and
location of signal peptide cleavage sites in amino acid sequences from
different organisms: Gram-positive prokaryotes, Gram-negative prokaryotes,
and eukaryotes. The method incorporates a prediction of cleavage sites
and a signal peptide/non-signal peptide prediction based on a combination
of several artificial neural networks and hidden Markov models. The method
is described in detail in the following article:
