a
Based on the gene name/locus tag of the sequenced genome of C. jejuni IA3902 (GenBank accession no. CP001876.1).
b
Y, yes (present with over 85% identity at the amino acid level); D, divergent (present with less than 85% identity); N, no (not present).
c
These genes are located in tandem as a separate cluster outside the CPS locus in this strain.
d
The entire CPS cluster of IA3902 is virtually identical to that of C. jejuni PT14 (NCBI GenBank accession no. NC_018709.2) and highly homologous to that of C. jejuni 01/51 (NCBI GenBank accession no. ERS742291 and ERS742289). Thus, these two strains are not included in the table.
e
aa, amino acids.
f
HAD, haloacid dehalogenase.
