APA TEGESÉ UREASE ING BASA INGGRIS?
Urease
Urat, sacara fungsional, kalebu superfamili saka amidohhidrolase lan phosphotriestreases. Iki minangka enzim sing nggabungake hidrolisis urea dadi karbon dioksida lan amonia. Reaksi iku kaya ing ngisor iki: 2CO + H2O → CO2 + 2NH3 Lebih khusus, urease ngartekali hidrolisis urea kanggo ngasilake amonia lan karbamat; ing karbamat sing diprodhuksi sabanjuré dibubaraké déning hidrolisis spontan kanggo ngasilaké asam amonia lan karbonat liya. Aktivitas Urease cenderung nambah pH lingkungane amarga mrodhuksi amonia, sawijining molekul dhasar. Uraos ditemokake ing akeh bakteri, jamur, ganggang, tetanduran lan sawetara invertebrata, uga ing lemah, minangka enzim lemah. Iki minangka metalloenzim sing ngandung nikel bobot molekul sing dhuwur. Ing taun 1926, James B. Sumner, profesor asisten ing Universitas Cornell, nedahake urease minangka protein kanthi nguji bentuk kristal. Karya Sumner minangka demonstrasi pertama yen protein murni bisa dienggo minangka enzim, lan banjur mimpin pengakuan sing paling akeh enzim sejatine yaiku protein, lan penghargaan hadiah Nobel ing bidang kimia kanggo Sumner nalika taun 1946. Struktur urease pisanan ditangani dening PA Karplus ing taun 1995.
Definisi saka urease ing bausastra Basa Inggris
Definisi urease ing kamus iku sawijining enzim sing dumadi ing akèh tetanduran, esp fungi, sing ngowahi urea dadi amonium karbonat.
