A ORF 13 (lpg0764/lpg0764b/lpg0763) of Philadelphia 1 not displayed, ORF 13-A of strain Lens was used. a Partial selleck compound duplication of ORF 2 (lpg0778). b, c Transposase; transposase disrupted. † Lag-1 of Görlitz 6543 has no functional

start codon. Underlined numbers indicate different clusters of corresponding ORF (see also Figure  2). The highly conserved 15 kb region (ORF14 – ORF 28) is not completely shown and only reflected by WecA and GalE. A conserved region found in all serogroup 1 strains Within the conserved region several genes were found which are proposed to be involved in the biosynthesis of the highly acetylated core region which is composed of mannose, Arachidonate 15-lipoxygenase N-acetyl-glucosamine (GlcNAc), N-acetyl-quinovosamine (QuiNAc) and rhamnose residues [19]. A vast number of ORFs, more specifically ORF 21 through 25 and 28, were recently reported to facilitate the biosynthesis of the repetitive legionaminic acid residues of the O-antigen [18, 36]. The pyrodoxal-phosphate dependent aminotransferase (ORF 21), the acetyltransferase neuD (ORF 22) and a dehydratase (lpg0966) located outside of the locus are likely to synthesize the precursor molecule of legionaminic acid, UDP-N,N’-diacetylbacillosamine (UDP-Bac2Ac4Ac) [37].
