Physical map presenting the genomic location of the
Campylobacter
Dsb oxidative pathway genes [dsbA1
(orange),
dsbA2
(blue),
dsbB
(green), and
astA
genes (purple)]. The astA gene was also included as it is a part of the same transcriptional unit with dsbA2 and dsbB, and its product is a substrate for DsbA2. Type A includes C. jejuni strains (A1: C. jejuni
subsp.
jejuni
81-176, 81116, ICDCCJ07001, MTVDSCj20, and C. jejuni 4031; A2: C. jejuni
subsp.
jejuni
NCTC 11168 = ATCC 700819, 00-2425, 00-2426, 00-2538, 00-2544, IA3902, NCTC 11168-BN148, PT14, R14, and C. jejuni 32488; A3: C. jejuni
subsp.
jejuni
S3 and M1, C. jejuni RM1221, C. jejuni subsp. doylei 269.97). Type B includes strains of C. coli species (C. coli
RM5611, 15-537360, CVM N29710, RM1875 and RM4661). Type C is represented by one C. lari strain (C. lari
RM2100). Type D includes three members of C. fetus species (C. fetus
subsp.
fetus
82-40, 04/554 and C. fetus subsp. testudinum 03-427). Type E is represented by one C. concisus strain (C. concisus
13826) and type F by one strain of C. curvus (C. curvus
525.92). The dsbA1 and astA genes of C. concisus, C. curvus, and C. fetus, strains are located on the chromosome apart from dsbA2dsbB genes. Genes and intergenic regions are drawn to scale (based on underlined strains). Pseudogenes or fragmented genes are marked with dashed lines.
