DNA sequence of proline permease gene from Pseudomonas fluorescens and predicted structure of proline permease.

The proline permease gene of Pseudomonas fluorescens has been isolated from the promoter region isolated by using a promoter probe (transposon Tn5-B21). By DNA sequencing of 2222 bp the primary structure of permease (494 aa) was deduced. The DNA sequence is 71.0% and 70.7% identical and the amino acid sequence is 75.8% and 76.0% similar to those of Escherichia coli and Salmonella typhimurium, respectively.
