  2. Porphobilinogen deaminase - Wikipedia

    en.wikipedia.org/wiki/Porphobilinogen_deaminase

    The most well-known health issue involving porphobilinogen deaminase is acute intermittent porphyria, an autosomal dominant genetic disorder where insufficient hydroxymethylbilane is produced, leading to a build-up of porphobilinogen in the cytoplasm. This is caused by a gene mutation that, in 90% of cases, causes decreased amounts of enzyme.

    Attacks may be triggered by alcohol, smoking, hormonal changes, fasting, stress, or certain medications. [2] [4] If the skin is affected, blisters or itching may occur with sunlight exposure. [2] Most types of porphyria are inherited from one or both of a person's parents and are due to a mutation in one of the genes that make heme. [2]

    α-Hemolysin from S.aureus. Pore-forming proteins (PFTs, also known as pore-forming toxins) are usually produced by bacteria, and include a number of protein exotoxins but may also be produced by other organisms such as apple snails that produce perivitellin-2 [1] [2] or earthworms, who produce lysenin.

  5. Acute intermittent porphyria - Wikipedia

    en.wikipedia.org/wiki/Acute_intermittent_porphyria

    Acute intermittent porphyria (AIP) is a rare metabolic disorder affecting the production of heme resulting from a deficiency of the enzyme porphobilinogen deaminase. It is the most common of the acute porphyrias .

  6. Erythropoietic protoporphyria - Wikipedia

    en.wikipedia.org/wiki/Erythropoietic_protoporphyria

    Erythropoietic protoporphyria (or commonly called EPP) is a form of porphyria, which varies in severity and can be very painful.It arises from a deficiency in the enzyme ferrochelatase, leading to abnormally high levels of protoporphyrin in the red blood cells (erythrocytes), plasma, skin, and liver. [2]

  7. Porphyria cutanea tarda - Wikipedia

    en.wikipedia.org/wiki/Porphyria_cutanea_tarda

    Porphyria cutanea tarda is the most common subtype of porphyria. [1] The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs.

  9. Porin (protein) - Wikipedia

    en.wikipedia.org/wiki/Porin_(protein)

    Therapeutic treatments, like vaccinations and antibiotics, are used to supplement this immune response. [5] Specific antibiotics have been designed to travel through porins in order to inhibit cellular processes. [8] However, due to selective pressure, bacteria can develop resistance through mutations in the porin gene. [5]
