Neisseria species including Neisseria gonorrhoeae (which causes gonorrhea), [22] Streptococcus pneumoniae, [23] and Haemophilus influenzae type B [24] all release a protease that destroys IgA. Additionally, Blastocystis species have been shown to have several subtypes that generate cysteine and aspartic protease enzymes which degrade human IgA ...
IgA protease (EC 3.4.21.72, IgA-specific serine endopeptidase, IgA proteinase, IgA-specific proteinase, immunoglobulin A protease, immunoglobulin A proteinase) is an enzyme. [ 1 ] [ 2 ] This enzyme catalyses the following chemical reaction [reaction equation needed]
IgA-specific metalloendopeptidase (EC 3.4.24.13, immunoglobulin A1 proteinase, IgA protease, IgA1-specific proteinase, IgA1 protease, IgA1 proteinase) is an enzyme. [1] [2] [3] This enzyme catalyses the following chemical reaction: Cleavage of Pro-Thr bond in the hinge region of the heavy chain of human immunoglobulin A
IgA protease may refer to: IgA specific serine endopeptidase, an enzyme; IgA-specific metalloendopeptidase, an enzyme This page was last edited on 4 February 2015 ...
Selective immunoglobulin A (IgA) deficiency (SIgAD [1]) is a kind of immunodeficiency, a type of hypogammaglobulinemia.People with this deficiency lack immunoglobulin A (IgA), a type of antibody that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract.
Secretory components wrap around two IgA units joined by a J chain protein fragment, resulting in a >--< configuration, with each of the two antigen binding regions of the two constituent y-shaped antibodies exposed. One identified function of secretory components is to protect IgA antibodies from degradation by the gastric acids and enzymes of ...
Electrophoresis is a laboratory technique in which the blood serum (the fluid portion of the blood after the blood has clotted) is applied to either an acetate membrane soaked in a liquid buffer, [3] or to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein ...
