The phrase "a helix from" is correct and usable in written English.
It can be used when referring to a specific helix that originates from a particular source or context, such as in scientific or technical writing.
Example: "The researchers discovered a helix from the DNA sample that exhibited unusual properties."
Alternatives: "a helix derived from" or "a helix originating from".
Process II is thus a transient local folding event involving formation of a helix from a disordered region in the ground state.
Page 6: The authors make a connection between the number of acidic residues in a helix from Ebola Vps35 compared to Marburg Vps35 and the frequency of outbreaks, which is a complete over interpretation of their data.
In structures of the BTB domain from Gigaxonin, amino acid S79 caps the N-terminus of a helix from the BTB domain, S52 and V82 form contacts internal to the BTB domain, whereas R15 and A49 map to the homodimerization interface.
Recent cryo-EM maps show that the surface of Rpn12 defined by Lys/Gln is occupied by a helix from Rpn2 in one conformational state of the RP (Supplementary Figure S3 at http://www.BiochemJ.org/bj/448/bj4480055add.htm; F. Foerster, personal communication).
Whether our biophysical measurements are reporting on an opportunistic interaction of the Rpn10 UIM with a site that normally accommodates an helix from Rpn2, and the functional significance of any potential alternative helical interactions remain to be determined.
Use of VLP expressing 180 copies of the 20-residue A-helix from HA2 in Group 1 viruses which is a major part of the epitope recognized by CR6261 and F10 BnAbs induced cross-reactive Abs against Group 1 but not Group 2 viruses.
The two tryptophans, both in the A helix, remain sequestered from solvent in the high-pressure intermediate, which retains some native NOESY cross peaks in the AGH core as well as between F33 and F43.
A hydrophobic helix from a symmetry-related Get3 molecule sits in the TMD-binding groove and mimics the TA binding scenario.
We have previously shown that dissociation of yeast enolase produced subtle changes in the structure of the monomer; there was a small increase in disordered structure and several peptide bonds, including one in a helix far from the interface, became susceptible to proteolysis [19].
Three cases occurred in 'far' bare zones more than half a helix away from the boundary, and one occurred in an 'inner' cofilin cluster more than half a helix away from the boundary (Video 11).
Blue arrowheads: severing in a bare half helix immediately neighboring a cofilin cluster; green arrowheads: severing in bare zones more than half a helix away from cofilin clusters; white arrowheads: cofilin clusters.
