Significados de helical structure em inglês

These PS2-siRNA duplexes exhibit an A-form helical structure similar to unmodified siRNA.

This structure is completely different from the amphipathic, helical structure observed for Type I AFPs.

However, in 50% TFE both the peptides show pronounced helical structure.

Photo 51: The x-ray diffraction image that led to the discovery of the double- helical structure of DNA.

Circular dichroism studies showed that IF indeed could adopt a helical structure, but only in membrane-mimicking environments.

The substitution of Ala residues in the hydrophobic face of the alpha-helix can prevent dimerization and specify monomeric helical structure.

Very similar results have been obtained in the two environments: an unbroken helical structure of the investigated region can be ruled out.

It has been reported that both the amphipathicity and helical structure of Mag 2 play an important role in its antimicrobial activity.

CD spectra in aqueous medium indicate that the apopeptide I adapts, mostly, a beta-sheet conformation whereas the glycopeptide II assumes helical structure.

In addition to being crosslinked, the strands also form a helical structure because of secondary bonds between different regions of the same molecules.

We report that the N-terminal domain of dSLBP is stably unfolded but has nascent helical structure at physiological pH and native-like solution conditions.

In addition to these cross-beta reflections, other reflections suggest the presence of well-defined coiled-coil helical structure arranged with a defined orientation within the fibrils.

The most frequently appearing form of DNA is a double helical structure in which two single strands are held together by Watson-Crick base pairs.

A number of electrostatic interactions could be identified which may contribute to the stability of the helical structure of the monomers and of the dimer.

Mutations in the TIEG2 alpha-HRM domain that disrupt its helical structure abolish its ability to both bind mSin3A and repress transcription.

In both solvents, residues 68-78 take on an amphipathic helical structure, in agreement with predictions made by comparison to homologous saposin family proteins.
