Peptide Hydrolases. Esteroproteases . Proteolytic Enzymes . Peptidases . Proteinases . Proteases . Hydrolases that specifically cleave the peptide bonds found in PROTEINS and PEPTIDES. Examples of sub-subclasses for this group include EXOPEPTIDASES and ENDOPEPTIDASES. . 0.48
Protons. Hydrogen Ion . Ion, Hydrogen . Ions, Hydrogen . Proton . Hydrogen Ions . Stable elementary particles having the smallest known positive charge, found in the nuclei of all elements. The proton mass is less than that of a neutron. A proton is the nucleus of the light hydrogen atom, i.e., the hydrogen ion. . 0.48
Protoporphyrinogen Oxidase. Protoporphyrinogen Dehydrogenase . Protoporphyrinogen IX Oxidase . Protoporphyrinogenase . Protox . Dehydrogenase, Protoporphyrinogen . Oxidase, Protoporphyrinogen . Oxidase, Protoporphyrinogen IX . A membrane-bound flavoenzyme that catalyzes the oxygen-dependent aromatization of protoporphyrinogen IX (Protogen) to protoporphyrin IX (Proto IX). It is the last enzyme of the common branch of the HEME and CHLOROPHYLL pathways in plants, and is the molecular target of diphenyl ether-type herbicides. VARIEGATE PORPHYRIA is an autosomal dominant disorder associated with deficiency of protoporphyrinogen oxidase. . 0.47
Protoplasts. Protoplast . The protoplasm and plasma membrane of plant, fungal, bacterial or archaeon cells without the CELL WALL. . 0.46

Thyroliberin TRH Merck . Thyrotropin-Releasing Factor . Thyrotropin-Releasing Hormone Tartrate . Abbott 38579 . Abbott38579 . Hydrate, Proterelin Tartrate . Prem, TRH . Stimu TSH . StimuTSH . TRH, Relefact . Tartrate Hydrate, Proterelin . Thyrotropin Releasing Factor . Thyrotropin Releasing Hormone . Thyrotropin Releasing Hormone Tartrate . Protirelin . Thyroliberin . A tripeptide that stimulates the release of THYROTROPIN and PROLACTIN. It is synthesized by the neurons in the PARAVENTRICULAR NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, TRH (was called TRF) stimulates the release of TSH and PRL from the ANTERIOR PITUITARY GLAND. . 0.46
Prothionamide. Ektebin . Peteha . Protionamide . Antitubercular agent similar in action and side effects to ETHIONAMIDE. It is used mostly in combination with other agents. . 0.46
Cytoplasm. Cytoplasms . Protoplasms . Protoplasm . The part of a cell that contains the CYTOSOL and small structures excluding the CELL NUCLEUS; MITOCHONDRIA; and large VACUOLES. (Glick, Glossary of Biochemistry and Molecular Biology, 1990) . 0.46
Molecular Motor Proteins. Motor Proteins, Molecular . Proteins, Molecular Motor . Proteins, Motility . Motility Proteins . Molecular Motors Proteins . Molecular Motors . Proteins that are involved in or cause CELL MOVEMENT such as the rotary structures (flagellar motor) or the structures whose movement is directed along cytoskeletal filaments (MYOSIN; KINESIN; and DYNEIN motor families). . 0.46
