Plant hormonal regulations and Ca2+ dependent modification of enzymatic activities are coordinately or independently integrated into the stress signaling pathways.
In particular, monoubiquitination is not related to proteasome targeting but to modification of enzymatic activity and subcellular localization [6], [7].
The authors concluded that the NO-mediated modification of enzymatic activity of Glo1 is possibly the consequence of structural changes that are induced by this modification.
In this coordinated process, modification of enzymatic rates occurring through specific or non-specific interactions would alter the ability of glue to make adhesive bonds.
Tokuriki and Tawfik [ 32] reported the modification of enzymatic specificity (i.e., change in enzymatic function) induced by the overexpression of GroEL through experimental evolution.
Eukaryotic cells have evolved sophisticated cellular mechanisms in response to the stresses that regulate several aspects of cell physiology as e.g. gene expression, metabolism, cell cycle progression, cytoskeletal organization, protein expression and homeostasis, and modification of enzymatic activity.
Moreover, several previous works have stated that metabolic network evolution is due to the modification of enzymatic specificity, and this was confirmed in several biosynthetic pathways, such as the citrate cycle and lysine biosynthetic pathway (e.g., reviewed in [ 39]), which possess chaperonin-dependent substrate enzymes.
Agitation, carbon and nitrogen source, and inducers (aromatic compounds, copper) are environmental factors that have been associated with the modification of the enzymatic production and/or the decolorization activity.
It is likely that RA is also the result of post-translational modifications of antigens by enzymatic activity (deiminases), and subsequent immune-mediated destruction of the synovium [ 9].
The applications of enzymatic modifications are limited to recombinant proteins harboring additional protein/peptide tags.
