| evolution | the enzyme belongs to the glycosyl hydrolase family 13, GH13 | Homo sapiens |
| physiological function | as one of receptors of the acquired membrane, human salivary alpha-amylase (HSA) plays an important role in the formation of caries. The conformation of the enzyme is altered in the presence of SPC-tetramer. The conformation changes of enzyme HSA might contribute to the reduction of the adhesion of cariogenic bacteria and finally decrease the occurrence of dental caries.
