Technique(s) used for Glycosylation DetectionMass shift detected on Western blot (using wild-type and mutant B. fragilis cells for expression, and anti-His tag antibody detection)
Technique(s) used for Glycosylated Residue(s) DetectionSite-directed mutagenesis
Protein Glycosylation- ImplicationProtein glycosylation is central to the physiology of B. fragilis and is necessary for the organism to competitively colonize the mammalian intestine. Deletion of the lfg (protein glycosylation machinery) region results in a substantial growth deficiency in vitro and a complete inability to compete with wild-type bacteria in the mouse intestine.

Additional CommentsGlycosylation sequon features: the sequon has an aspartate (D) preceding the glycosylated T or S which is followed by an amino acid with one or more methyl groups (alanine, isoleucine, or leucine; (D)(S/T)(A/I/L/V/M/T). Moreover, None of the 17 unglycosylated S and T residues examined in of BF2494 (excluding two in the signal peptide) have a preceding D, although seven are followed by A, I, or L and one by V. Non methylated amino acids were not tolerated at third position of sequon in BF2494. Il
