Genetic organization of the putAP operons of different microorganisms and amino acid sequence relatedness of their gene products. The microorganisms were V. vulnificus, V. cholerae, E. coli, and S. enterica serotype Typhimurium. (A) The coding regions of putAP genes (shaded boxes) and chromosomal DNA (thick lines) are shown. The direction of transcription is indicated by the arrows. (B) Dendrograms showing relatedness of PutA and PutP were derived using the CLUSTALW alignment program (http//www.ebi.ac.uk/clustalw) and based on the amino acid sequences in the GenBank database (National Center for Biotechnology Information database).
