Other species, for instance bacteria that cause meningitis, gonorrhea, some cases of pneumonia, sinusitis and ear infections also produce an enzyme that cleaves IgA, but this is a serine protease and is metal-independent.[4] References1. ^{{cite journal | vauthors = Kornfeld SJ, Plaut AG | title = Secretory immunity and the bacterial IgA proteases | journal = Reviews of Infectious Diseases | volume = 3 | issue = 3 | pages = 521–34 | year = 1981 | pmid = 6792682 | doi = 10.1093/clinids/3.3.521 }} 2. ^{{cite journal | vauthors = Gilbert JV, Plaut AG, Wright A | title = Analysis of the immunoglobulin A protease gene of Streptococcus sanguis | journal = Infection and Immunity | volume = 59 | issue = 1 | pages = 7–17 | date = January 1991 | pmid = 1987065 | pmc = 257698 }} 3. ^{{cite journal | vauthors = Gilbert JV, Plaut AG, Fishman Y, Wright A | title = Cloning of the gene encoding streptococcal immunoglobulin A protease and its expression in Escherichia coli | journal = Infection and Immunity | volume = 56 | issue = 8 | pages = 1961–6 | date = August 1988 | pmid = 3294181 | pmc = 259508 }} 4. ^{{cite journal | vauthors = Parsons HK, Vitovski S, Sayers JR | title = Immunoglobulin A1 proteases: a structure-function update | journal = Biochemical Society Transactions | volume = 32 | issue = Pt 6 | pages = 1130–2 | date = December 2004 | pmid = 15506988 | doi = 10.1042/BST0321130 }} External links
