Perna
|
D049883 |
[A genus of freshwater mussel in the family MYTILIDAE, class BIVALVIA. It is found in tropical and warm temperate coastal waters. Most species have green in their shells.

Peromyscus
|
D010542 |
[A genus of the subfamily SIGMODONTINAE consisting of 49 species. Two of these are widely used in medical research. They are P. leucopus, or the white-footed mouse, and P. maniculatus, or the deer mouse.

Peroneal Nerve
|
D010543 |
[The lateral of the two terminal branches of the sciatic nerve. The peroneal (or fibular) nerve provides motor and sensory innervation to parts of the leg and foot.

|
Peroneal Neuropathies
|
D020427 |
[Disease involving the common PERONEAL NERVE or its branches, the deep and superficial peroneal nerves. Lesions of the deep peroneal nerve are associated with PARALYSIS of dorsiflexion of the ankle and toes and loss of sensation from the web space between the first and second toe. Lesions of the superficial peroneal nerve result in weakness or paralysis of the peroneal muscles (which evert the foot) and loss of sensation over the dorsal and lateral surface of the leg. Traumatic injury to the common peroneal nerve near the head of the FIBULA is a relatively common cause of this condition. (From Joynt, Clinical Neurology, 1995, Ch51, p31)

Peroxidase
|
D009195 |
[A hemeprotein from leukocytes. Deficiency of this enzyme leads to a hereditary disorder coupled with disseminated moniliasis. It catalyzes the conversion of a donor and peroxide to an oxidized donor and water. EC 1.11.1.7.

Peroxidases
|
D010544 |
|
|
Peroxides
|
D010545 |
[A group of compounds that contain a bivalent O-O group, i.e., the oxygen atoms are univalent. They can either be inorganic or organic in nature. Such compounds release atomic (nascent) oxygen readily. Thus they are strong oxidizing agents and fire hazards when in contact with combustible materials, especially under high-temperature conditions. The chief industrial uses of peroxides are as oxidizing agents, bleaching agents, and initiators of polymerization. (From Hawley's Condensed Chemical Dictionary, 11th ed)

Peroxins
|
D000074401 |
[Proteins that are essential for the assembly of PEROXISOMES. They recognize and transport cytoplasmic proteins that contain PEROXISOMAL TARGETING SIGNALS (PTS) to the peroxisome. Mutations in peroxin (PEX) genes are associated with several PEROXISOMAL DISORDERS.

|
Peroxiredoxin III
|
D061105 |
[A THIOREDOXIN-dependent hydroperoxidase that is localized in the mitochondrial matrix. The enzyme plays a crucial role in protecting mitochondrial components from elevated levels of HYDROGEN PEROXIDE.
] |
|
Peroxiredoxin VI
|
D054465 |
[A peroxiredoxin that is a cytosolic bifunctional enzyme. It functions as a peroxiredoxin via a single redox-active cysteine and also contains a Ca2+-independent acidic phospholipase A2 activity.
] |
|
Peroxiredoxins
|
D054464 |
[A family of ubiquitously-expressed peroxidases that play a role in the reduction of a broad spectrum of PEROXIDES like HYDROGEN PEROXIDE; LIPID PEROXIDES and peroxinitrite. They are found in a wide range of organisms, such as BACTERIA; PLANTS; and MAMMALS. The enzyme requires the presence of a thiol-containing intermediate such as THIOREDOXIN as a reducing cofactor.

|
Peroxisomal Bifunctional Enzyme
|
D063994 |
[A monomeric protein found in liver peroxisomes that contains two enzymatically active domains; an enoyl-CoA hydratase/3,2-trans-enoyl-CoA isomerase domain, and an (S)-3-hydroxyacyl-CoA dehydrogenase domain. The enzyme is stereospecific with regards to how cis and trans double bonds are metabolized. It is complemented by PEROXISOMAL MULTIFUNCTIONAL PROTEIN-2, which has the opposite stereospecificity.
