Abstract: | The papA gene of the uropathogenic strain Escherichia coli J96, coding for the Pap pili subunit, was subjected to DNA sequencing, and found to code for an 185-amino acid-long polypeptide with a 22-amino acid-long signal peptide. Here we present the primary sequence, the hydrophilicity profile, and the predicted polypeptide secondary structure of the Pap pili subunit. |
