These post-translational modifications include most prominently methylation, acetylation and phosphorylation, but less frequent additional modifications such as crotonylation and citrullination are also being explored, and constitute a complex histone code [ 6].
However, the human collagenase-3 is subjected to different levels of regulation and constitutes a more complex system than originally thought.
The tmRNA can act as a tRNA and mRNA and constitutes a ribonucleoprotein complex together with the three protein components SmpB, EF-Tu and (usually) the ribosomal protein S1, while the latter is absent from bacilli and is substituted by a homologue encoded by the ypfD gene [ 79].
Acquisition of diaspore and floral syndromes has been very dynamic in the course of evolution, and thus any flora constitutes a complex assemblage of specialized and generalized species (Whitney 2009).
For macroalgae and seagrasses, global change constitutes a complex mixture of immediate positive and negative effects.
In addition, the mitochondrial retrograde signaling triggers both adaptive and maladaptive cellular responses, which constitutes a complex network of processes (Guha and Avadhani, 2013).
