Enzymatic Synthesis of Triphosphopyridine Nucleotide
Von Euler and Vestin (1) demonstrated the synthesis of triphosphopyridine nucleotide (TPN) when diphosphopyridine nucleotide (DPN) was incubated with adenosine triphosphate (ATP) in the presence of crude yeast maceration juice. In subsequent reports (2) from the Stockholm laboratory, several mechanisms for this reaction were considered but none was established. With crude pigeon liver fractions...

متن کاملPurification, enzymatic characterization, and nucleotide sequence of a high-isoelectric-point alpha-glucosidase from barley malt.
High-isoelectric-point (pI) alpha-glucosidase was purified 7, 300-fold from an extract of barley (Hordeum vulgare) malt by ammonium sulfate fractionation, ion-exchange, and butyl-Sepharose chromatography. The enzyme had high activity toward maltose (k(cat) = 25 s(-1)), with an optimum at pH 4.5, and catalyzed the hydrolysis by a retaining mechanism, as shown by nuclear magnetic resonance. Acarb...

متن کاملtechnical and legal parameters for determination of river boundary,( case study haraz river)
چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...
