[Analysis of signal peptides of the secreted proteins in Ralstonia solanacearum GMI1000].

The 3,440 open reading frames (ORFs) of Ralstonia solanacearum GMI1000 were used for predicting signal peptides by comprehensive analyses with SignalP 3.0, TMHMM 2.0, TargetP 1.01, LipoP 1.0 and PSORTb, and screening based on L value. Total 186 signal peptides with conserved amino acid residues are found and among them, 134 are secretary types, 22 are RR-motif types and 30 are lipoprotein signal peptides. The length distribution of signal peptide and its domains were analyzed systemically. No type pilin-like signal peptides and bacteriocins and pheronones signal peptides are found in the database of deduced proteins encoded by the genome of R. solanacearum GMI1000.
