Function Structural subunit of type IV pili involved in surface adhesion
Glycosylation Status
Glycosylation Type N- (Asn) linked

Technique(s) used for Glycosylation DetectionAberrant migration on lithium dodecyl sulfate (LDS)-PAGE as detected through western blotting
Protein Glycosylation- Implication Glycosylation is crucial for pilin function. N-glycosylation of PilA4 might play a major role in the assembly and/or function of pili, and regulate the transition from planktonic cell to biofilm formation under stress conditions.
Protein Glycosylation linked (PGL) gene(s)
OST Gene NameAglB
Additional CommentAglB-dependent N-glycosylation is not required for PilA4 assembly. Pilin expression in pilA[1-6] cells results in strong surface adhesion, but not microcolony formation.
