Cloning and sequencing of the Pseudomonas aeruginosa PAK pilin gene

A 1.2-kilobase (kb) HindIII restriction fragment containing the pilin gene from Pseudomonas aeruginosa PAK has been cloned and sequenced. The pilin protein is 144 amino acids in length with a positively charged leader sequence of 6 amino acids. There is probably only one copy of the gene per chromosome.
