The phrase "are unstructured in the" is correct and usable in written English.
It can be used when describing something that lacks a defined structure or organization in a specific context.
Example: "The data sets we are analyzing are unstructured in the sense that they do not follow a predefined format."
Alternatives: "lack structure in the" or "are disorganized in the".
Recent crystal structure of PcrH showed that it is also a dimer, although the dimer interactions are made through the convex side of the TPR fold instead of the N-terminal region and TPR 1. Also, there are no additional helices N-terminal to TPR 1 in PcrH as the N-terminal 20 residues are disordered and residues 21 31 are unstructured in the crystal structure [17].
Similar results were seen with the H1 tails that are unstructured in the chromatosome.
We demonstrated that Aβ4 42, Aβ1 42 and AβpE3 42 are unstructured in the monomeric state.
We demonstrated that all five Aβ variants studied (Aβ4-38, Aβ1-42 AβpE3-42Aβ1-42 and AβpE3-42) are unstructured in the monomeric state.
Experimentally, it is known that the NLS polypeptide is unstructured in the NF-κB complex with DNA but it forms an extended helical structure with the NLS (residues 301 304) between the two helices in the NF-κB/IκBα complex.
The short (6-residue) helix III has been shown to be unstructured in the intermediate ensemble and does not dock onto the developing hydrophobic core until after the rate-limiting transition state has been traversed.
Twitter communication is unstructured in the sense that every user can send a message to any other user.
The accessory motif PAR is unstructured in the absence of DNA and assumes a more ordered conformation when bound to DNA [16].
Sir3 BAH also contacts the H2A/H2B acidic patch using the loop 1 region that is unstructured in the absence of the NCP.
The extended conformation of Scc21 181 clearly depends on its contacts with the surrounding Scc4; it is likely to be unstructured in the absence of its partner.
Φ-Values close to zero indicate that the transition state (or intermediate) is unstructured in the region of the amino acid substitution, while higher Φ-values indicate that the region is structured in the transition state (or intermediate) [161,162].
