Function
S-layer protein. The S-layer is a paracrystalline mono-layered assembly of proteins which coats the surface of bacteria (PubMed:24078613). Under laboratory conditions, has a supportive but not a critical role in the function of the cyanobacterium (PubMed:24078613). Shows no apparent hemolytic activity against sheep erythrocytes, however, a slight hemolytic activity is detected during the conformational change caused by the rebinding of Ca(2+) (PubMed:16672608).
