Protein attributes

Sequence length1462 AA.
Sequence statusComplete.
Sequence processingThe displayed sequence is further processed into a mature form.
Protein existenceInferred from homology

General annotation (Comments)

Function

Production of extracellular glucans, that are thought to play a key role in the development of the dental plaque because of their ability to adhere to smooth surfaces and mediate the aggregation of bacterial cells and food debris.

Catalytic activity

Sucrose + ((1->6)-alpha-D-glucosyl)(n) = D-fructose + ((1->6)-alpha-D-glucosyl)(n+1).

Subcellular location

Secreted.

Miscellaneous

GTF-I synthesizes water-insoluble glucans (alpha 1,3-linked glucose and some 1,6 linkages), GTF-S synthesizes water-soluble glucans (alpha 1,6-glucose). GTF-SI synthesizes both forms of glucans.

Sequence similarities

Belongs to the glycosyl hydrolase 70 family.

Contains 14 cell wall-binding repeats.
