Despite its fierce campaign of violence, the group has an undefined structure and no clear chain of command.
For a sequence of more than two residues with undefined secondary structure (i.e., coil, bend, hydrogen bonded turn, or other undefined structure), a force constant of 250 kJ mol−1 nm−2 was applied.
The C-terminal 'tail' of glycogenin is of undefined structure, but the structure of this peptide in complex with glycogen synthase was solved.
Additional bioinformatics analysing tools will help in evaluating protein reciprocal biochemical and immunochemical relationships by showing for instance the clustering behaviour of previously undefined structure.
The polymers synthesized by this process face the problems such as the inability to precisely control molecular weight and distribution, the limited capacity to make complex architectures, the range of undefined defect structures, and other forms of "structural irregularity".
On the one hand, it is thought that oligomer formation is driven by relatively unspecific protein-protein interactions between monomers resulting in undefined, disordered structures [10].
First, genetic data inferred from dissection of the ta-siRNA pathway suggest that DCL4, which is the major DCL in antiviral defense, produces 21-nt siRNAs from dsRNA substrates instead of other undefined secondary structures [3].
In addition, PLIN5 interaction with ATGL on LDs and on undefined intracellular structures lacking neutral lipids (Granneman et al. 2011) has been reported.
