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.

[PubMed: 21115495] Additional Comments Glycosylation 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 Year of Identification 2011 Year of Validation 2011
