The molecular structure of polyadenylic acid.

چکیده
The structure of fibers of polyadenylic acid at acid pH has been studied by S-ray diffraction. A model is proposed consisting of two parallel intertwined helical chains, each having a screw of 3.8 .k and 45 " and related to each other by a +-ad asis parallel to the fiber axis. Coordinates, bond distances and angles and the calculated Fourier transform are given for this model. Reasons are given why the quite different model of lKorgan & Bear is thought to be wrong.

Interaction of polyadenylic acid with the mercury electrode.
Interactions of polyadenylic acid with the mercury electrode were followed by means of direct current (d.c.), alternating current (a.c.), and pulse polarography. It was ascertained that the electrode reaction of polyadenylic acid did not differ significantly from the reaction of its monomeric components. In contrary to the latter reaction, the polarographic reduction of poly adenylic acid take...

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...

All messenger RNAs (mRNAs) have a polyadenylic acid tail that is added during post transcriptional RNA processing. Investigation of the structure-function and interactions of polyadenylic acid is an important area to target for cancer and related diseases. Jatrorrhizine and coptisine are two important isoquinoline alkaloids that are structurally very similar, differing only in the substituents ...

6-Thioguanine, at a dose of 40 mg/kg body weight, was administered to rats at 12 hr after partial hepatectomy; 6 hr later, liver polysomes and cell sap were isolated and utilized to measure the effects of this antimetabolite on protein synthesis in vitro. When radioactive leucine was used to label peptides synthesized in vitro, no difference was observed between polyacrylamide gradient gel scan...

1. A ribonuclease has been prepared from human muscle by ammonium sulphate fractionation, heat treatment and ion-exchange chromatography. 2. The enzyme degrades polycytidylic acid and polyuridylic acid to the nucleoside 3'-phosphates, with nucleoside 2':3'-cyclic phosphates as intermediates. Polyadenylic acid and polyguanylic acid are not attacked. 3. The enzyme has maximal activity at pH8.5. T...
