Synthesis of125I-ubiquitin conjugates in extracts of Lemna minor

Synthesis and mass spectrometric structural chracterization of ubiquitin conjugates

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

The biosynthesis of D-apiose in Lemna minor.

Lemna minor incorporates radioactivity from n-glucose-l14C, D-glucose-2-*4C, D-glucose-3 ,4-r4c, D-glucose-6-14C, sodium acetate-Z-14C, DL-serine-3-14C, and L-methionine-14CH8 into the n-apiose moiety of cell wall polysaccharide. The mechanism of biosynthesis of this hydroxymethyltetrose was studied by determining the distribution of 14C in n-apiose after feeding various labeled precursors. Lab...

The Turnover of Nucleic Acids in Lemna minor.

A method is described for measuring the rate constants of both synthesis and degradation of nucleic acids in sterile growing cultures of Lemna minor which avoids the difficulties of environmental changes in isotope uptake and precursor pool size. In fast growing cultures the half-life of ribosomal RNA has been estimated to be between 5 and 8 days.This half-life has been shown to consist of two ...

The Phosphorylation of Ribosomal Protein in Lemna minor.

Sterile cultures of Lemna minor have been labeled with (32)P(1), and the ribosomal proteins have been examined for radioactivity. In relatively short term labeling a radioactive protein was found which ran as a single component in both urea/acetic acid and sodium lauryl sulfate gel electrophoresis. Acid hydrolysis of the labeled protein permitted the isolation of serine phosphate. After labelin...
