Representation of the NRPS locus present in the same region as XaPPTase in X. oryzae pv. oryzicola strain BLS256. Comparison with the similar genomic region of X. axonopodis pv. citri strain 306. NRPS modules are represented by circles. Large circles indicate complete NRPS modules (containing domains C, A and PCP). The amino acid predicted to be assembled by the corresponding module is indicated within each circle. Small black circles represent TE domains. Black arrows: NRPS genes. The starter module circled in red exhibits a C-domain belonging to the same phylogenetic clade as starter C-domains identified by Rausch et al.  (Additional file 2). Elongation modules circled in blue exhibit a C-domain belonging to the same phylogenetic clade as dual C/E domains identified by Rausch et al.  (Additional file 2). Amino acids predicted to be epimerized by these domains are in blue. : tRNA. Orientation of the tag indicates the orientation of the tRNA gene in the genomic regions. Amino acid specificity of each tRNA is indicated above or below each tag according to the orientation of the tRNA gene. IS: insertion sequence. Dotted arrows: pseudogenes. Dotted and incomplete circles: incomplete and non-functional modules.
