Analysis of the SRL structure (Protein Data Bank [PDB] identification no. 483D) revealed that the 2′-OH groups of U2650 and A2670 are not involved in crystal contacts and hence should be available for modifications.
The study demonstrates that, irrespective of how much time was available for modifications of intron lengths and individual amino acid residues, there had been an evolutionary pressure on maintenance of all three chloroplast peroxide detoxification systems, namely APx, GPx and Prx.
In addition to that, low-pass filtering and sample-rate conversion are available for modification of the overall composite waveform.
Second, the unique nanosize dimension of AuNPs provides a large surface area readily available for modification with loading targeting molecules or specific biomarkers for drug delivery systems [79].
Through this kind of cross-coding, (Colombi (2006): 154) argues, 'actions … can be talked about in more 'material' terms, as having occurred, as being available for modification and, most importantly, for movement in conceptual space as actors in their own right'.
Although there are many reagents available for modification of aa residues in proteins, only few exhibit reasonable selectivity for a particular residue under conditions close to physiological.
Depending on the chemical, this step may generate a large number of possible transformation products due to the number of sites available for modification.
In order to reduce computational effort, the sets of candidate oxidoreductase reactions available for modification should be determined according to previous reports [ 52].
These results suggest that the consensus motif represents the major binding site for the SUMO conjugating enzyme Ubc9 and that, when lysine 402 is not available for modification, Ubc9 can instead modify nearby lysines.
We considered an approach where all molecular driving events were maintained constant between species, leaving the metabolic demand parameter and the cell growth rate parameter as the only ones available for modification.
We employed a protein footprinting [ 29, 31– 34] by which modification of solvent-accessible XPA lysine residues by the primary amine-specific reagent NHS-biotin is prevented at the XPA DNA junction binding sites, while the surface lysines not involved in the binding are available for modification.
