Conservation of the gene context of putrescine carbamoyltransferases. The open reading frame (ORF) EF0732 of E. faecalis is shown with neighbouring ORFs. Under each numbered ORF (EF0731 to EF0735) is indicated the putative function proposed by the annotators of this complete genome [14]. Below is the reannotation we are proposing. This schematic representation is repeated for the similar genomic regions present in three other completely sequenced genomes, those of Lc. lactis, S. mutans and L. monocytogenes. The homologous sequences are indicated by using the same color : white for transcriptional regulator, yellow for PTCase, pink for permease, green for agmatine deiminase, blue for carbamate kinase, respectively.
