A Preliminary Investigation of the Jack-bean Urease Inhibition by Randomly Selected Traditional used Herbal Medicine
Helicobacter pylori :28 µg/mL). (H. pylori) infection leads to different clinical and pathological outcomes in humans, including chronic gastritis, peptic ulcer disease and gastric neoplasia and even gastric cancer and its eradiation dependst upon multi-drug therapy. The most effective therapy is still unknown and prompts people to make great efforts to find better and more modern natural or ...

متن کاملIx. the Half-unt and Hempolymers of Jack Bean Urease*
Investigation of their ultracentrifugal and electrophoretic behavior and chemical reactivity has been used to characterize the suprastructure of the nongenetic urease isozymes. As purified from jack bean meal, urease is obtained in the LY form (M, = 480,000, s20,W = 18.3), which is composed of two noncovalently bound, equal and active A1 half-units (M, = 240,000, sZo,W = 11.5) which separate af...
متن کاملThe amino acid composition of jack-bean urease.
Analyses were carried out on twice-recrystallized freeze-dried urease (Bailey & Boulter, 1969) that had previously been dialysed for 24hr. in the cold against running tap water, and then for 24hr. against three changes of deionized water. Acid hydrolysis of urease (5mg.) was carried out at 1100 in evacuated heavy-walled Pyrex tubes with threetimes-redistilled 5-7M-hydrochloric acid at a concent...
متن کاملThe nickel ion environment in jack bean urease.
Preliminary results of an extended X-ray absorption fine structure (e.x.a.f.s.) and X-ray absorption near edge structure study of jack bean urease have recently been reported [Hasnain & Piggott (1983) Biochem. Biophys. Res. Commun. 112, 279]. These results indicate that the environment of the nickel ion in the enzyme is similar to that in the model compounds Ni(L)2(L')1(ClO4)1 (where L is 1-n-p...
