Cardiac contractility is regulated by dynamic phosphorylation of sarcomeric proteins by kinases such as cAMP-activated protein kinase A (PKA). (biomedcentral.com)
However, since these kinases regulate a broad range of cellular responses, their compartmentalization in close proximity to their sarcomeric targets is required to facilitate control over which proteins are phosphorylated in response to second messenger signalling [ 8 , 9 ]. (biomedcentral.com)
At the same time, co-compartmentalization of enzymes or proteins that generate or terminate these second messenger metabolites, such as the phosphodiesterases (PDEs) which degrade cAMP and cGMP, with the relevant responsive kinases helps to optimise the precision and speed of response to second messenger signaling [ 10 ]. (biomedcentral.com)
Among these are energy-consuming enzymes such as GTPases, protein kinases, ATP-dependent RNA helicases, and AAA-type (ATPases associated with various cellular activities) ATPases, which suggests that the energy derived from nucleotide hydrolysis confers directionality to ribosome assembly.

When tryptophan is present, the trpR protein binds to the operator, blocking transcription of the trp operon by RNA polymerase. (wikipedia.org)
This prevents RNA polymerase from binding to and transcribing the operon, so tryptophan is not produced from its precursor. (wikipedia.org)
Attenuation is made possible by the fact that in prokaryotes (which have no nucleus), the ribosomes begin translating the mRNA while RNA polymerase is still transcribing the DNA sequence. (wikipedia.org)
The hybridization of sequences 1 and 2 to form the 1-2 structure is rare because the RNA polymerase waits for a ribosome to attach before continuing transcription past sequence 1, however if the 1-2 hairpin were to form it would prevent the formation of the 2-3 structure (but not 3-4).
