10 Urease Inhibition Muhammad
The design, synthesis, characterization and exploring the broad spectrum of potency of biologically active molecular building blocks have attracted the attention of scientific community since last couple of decades. The emergence of pathogenic resistance is a natural phenomenon and investigations toward the advances of new structurally diverse inhibitors have always been at the esteem of pharma...
متن کاملInhibition of Urease Activity in Soils
Studies to evaluate more than 100 compounds as inhibitors of urease activity in soils showed that dihydric phenols and quinones were the most effective organic compounds tested and that silver and mercury salts were the most effective inorganic compounds. When the most potent inhibitors were compared using 50 1'8 of inhibitor per g of soil, their effectiveness decreased in the order: catechol >...
متن کاملOccurrence of urease in T strains of Mycoplasma.
A previously unknown metabolite necessary for growth of T strains of Mycoplasma in artificial culture media has been identified as urea. The source of this metabolite was the mammalian plasma or serum enrichment of the culture medium. Normal horse serum was the most satisfactory native protein enrichment for cultivation of T strains of mycoplasma, and it is believed that its superior performanc...
متن کاملKinetics and mechanism of jack bean urease inhibition by Hg2+
UNLABELLED BACKGROUND Jack bean urease (EC 3.5.1.5) is a metalloenzyme, which catalyzes the hydrolysis of urea to produce ammonia and carbon dioxide. The heavy metal ions are common inhibitors to control the rate of the enzymatic urea hydrolysis, which take the Hg2+ as the representative. Hg2+ affects the enzyme activity causing loss of the biological function of the enzyme, which threatens ...
متن کاملA Conductometric Urea Biosensor by Direct Immobilization of Urease on Pt Electrode
Urease was immobilized on platinum electrode both by chemical binding and electropolymerization.The conductometric urea biosensor thus prepared showed a detection limit of 4.9×10-5 M and linear dynamic range from 4.9×10-5 to 5.8×10-3 M for urea concentration when the enzyme is covalently immobilized on Pt electrodes. Conductometric transducers respo...
