Investigation of solvent effect on the active site energy of Carbonic Anhydrase and Ribonucleotide Reductase
Enzymes catalyze many biological reactions. The rates of chemical reaction in the presence ofenzymes are, in some cases, accelerated more than 10 orders of magnitude relative to thecorresponding rates in solution.In this paper a comparison between optimized structures of two enzyme molecules in aspect ofenergy and dipole moment in different conditions including presence of metallic ion, without...
متن کاملThe relationship between carbonic anhydrases and zinc concentration of erythrocytes in patients under chronic hemodialysis.
The levels of carbonic anhydrase I and II isozymes in human erythrocytes were determined using the single radial immunodiffusion method in 53 patients (29 males, 24 females) under chronic hemodialysis, and zinc concentration in erythrocytes were also determined. Both carbonic anhydrase. I and II levels and zinc concentration in erythrocytes were observed to be significantly increased in chronic...
متن کاملZinc deficiency, carbonic anhydrase, and photosynthesis in leaves of spinach.
A shortage in the zinc supply to spinach (Spinacia oleracea L.) drastically reduced carbonic anhydrase levels with little effect on net CO(2) uptake per unit leaf area, except with the most severe zinc stresses. Under these conditions, carbonic anhydrase was below 10% and photosynthesis 60 to 70% of the control levels. When photosynthesis was measured at a range of CO(2) supply levels, zinc-def...
متن کاملStudy of Glycation Process of Human Carbonic Anhydrase II and Investigation of Effect of Fasting On Enzyme Activity by Using Spectroscopic Methods
Background: Glycation is the non-enzymatic reaction between the carbonyl groups in sugar and free amino groups in proteins. this reaction leads to changes in structure and functions of proteins. Advanced glycation end products (AGEs) is the final stage in this process, which is highly oxidizing and destructive nature, causing many diabetic complications. Methods: In the present investigation, ...
متن کاملThe relationship between carbonic anhydrase activity and zinc content of erythrocytes in normal, in anemic and other pathologic conditions.
By BERT L. VALLEE, M.D., HERBERT D. LEWIS, M.D., MARK D. ALTSCHULE, M.D., AND JOHN G. GIBSON, II, M.D. I T HAS been shown that zinc is a component of the carbonic anhydrase molecule.” 2 This enzyme has been demonstrated to catalyze the reaction H,O + CO, ± H,CO, in vitro; its molecular weight is approximately half that of hemoglobin,’ and some of its other physico-chemical properties are establ...
