Fusion of fluorescent reporters can, however, modify protein structure and function.
Posttranslational modifications, such as citrullination, methylation or glycosylation, are common alterations that modify protein structure and possibly stability, functionality and antigenicity of proteins.
Adaptor proteins and kinases play significant roles in signal transduction in cell immune systems, mediate specific interactions between proteins, and activate phosphorylation of the target proteins to functionally modify protein structure and activity [ 39, 40].
Conversely, changes in the coding sequence of genes can modify protein structure, function, and efficiency, and therefore can be used to identify evidence for parallel or convergent evolution as successfully demonstrated in recent studies for sequences in plants [ 24, 25], monkeys [ 26], and fish [ 27, 28].
The decrease of molecular size from 64 kDa (computed from the amino acid sequence for 6-His- PfaE3) to the 60 62 kDa observed during SDS PAGE is consistent with the loss of about 15 34 amino acids and it is possible that this negatively affects PfaE3 co-factor binding and dimerization and thus may modify protein structure and catalytic activity.
In addition, previous analyses have shown that AS rarely changes protein domains but can significantly modify protein structures (Birzele et al. 2008; Menon et al. 2011).
The magnitudes of endogenous forces that are known to act at the cellular level to modify protein structures have been measured and can serve as a basis for comparison to forces produced by RF fields (Titushkin and Cho 2006; Valberg 2006).
The interaction of proteins with NPs may modify protein activity and structure and interfere with their natural fate.
Cooking and pasteurization also destroy microbes that reduce storage stability, and thermal processing can modify protein content and structure to achieve desired technical or nutritional effects (Thomas et al., 2007; van Boekel et al., 2010).
Additionally, HNE modifies proteins at exposed nucleophilic sites, altering tertiary structure and ultimately modifying activity.
