CM000660.1_165 62.5 1.38E-24 flgR VF0114 Flagella Motility VFC0204 Two different (approximately 59-kDa) flagellin subunits, FlaA and FlaB are subject to both antigenic variation and phase variation; The expression of FlaA and FlaB is controlled by different transcription factors, namely the alternative sigma28 (FlaA) and sigma54 (FlaB) transcription factors; post-translationally modified through O-linked glycosylation. The major modification are pseudaminic acid (Pse5Ac7Ac), a nine carbon sugar that is similar to sialic acid, and an acetamidino-substituted pseudaminic acid (PseAm). There are also minor amounts of a dihydroxyproprionyl form (Pse5Pr7Pr) and an O-acetylated form (Pse5Ac7Ac8OAc); the exact role of glycosylation is unknown. The modification appears to be important for flagellar assembly and may be required for recognition by the flagellar secretion/assembly apparatus (flgR) sigma-54 associated transcriptional activator [Flagella (VF0114) - Motility (VFC0204)] [Campylobacter jejuni subsp. jejuni NCTC 11168] Campylobacter jejuni

Because of their sequence homology, similar domain structure and glycosyltransferase properties these toxins are designated 'large clostridial cytotoxins'.

The proteolytic activation of Ib precursor into Ib occurs at A211, which then facilitates Ia docking, formation of voltage-dependent ion-permeable channels in membranes, and formation of heptamers on cell membrane. Ia is also proteolytically activated by proteases, with a resultant loss of 9 to 13 amino acids from the N terminus.
