Organism
Candida albicans (strain SC5314 / ATCC MYA-2876)
Function
Secreted aspartic peptidases (SAPs) are a group of ten acidic hydrolases considered as key virulence factors. These enzymes supply the fungus with nutrient amino acids as well as are able to degrade the selected host's proteins involved in the immune defense. Involved in triggering host polymorphonuclear neutrophils chemotaxis toward germ tubes. Moreover, acts toward human hemoglobin though limited proteolysis to generate a variety of antimicrobial hemocidins, enabling to compete with the other microorganisms of the same physiological niche using the microbicidal peptides generated from the host protein. Required for cell surface integrity and cell separation during budding.
Similarity
Belongs to the peptidase A1 family.
