Structure of the putative TTI mRNA. (a) The 303-bp TTI cDNA has a 53-aa ORF composed of a 21-aa putative signal peptide sequence and a 32-aa mature TTI peptide, based on the N-terminal aa analysis of the previously purified TTI from the saliva. (b) The hydrophobicity (Kyte-Doolittle) plot of the 53-aa ORF sequence constructed by using the Protean option of dnastar software shows a hydrophilic region corresponding to the putative signal peptide segment. (c) The eukaryotic signal peptide prediction program psort predicted cleavage between amino acid residues 19 and 20.
