Caption: Contemporary analyses of cell metabolism have called out three metabolites: ATP, NADH, and acetyl-CoA, as sentinel molecules whose accumulation represent much of the purpose of the catabolic arms of metabolism and then drive many anabolic pathways. Such analyses largely leave out how and why ATP, NADH, and acetyl-CoA (Figure 1) at the molecular level play such central roles. Yet, without those insights into why cells accumulate them and how the enabling properties of these key metabolites power much of cell metabolism, the underlying molecular logic remains mysterious. Four other metabolites, S-adenosylmethionine, carbamoyl phosphate, UDP-glucose, and Δ2-isopentenyl-PP play similar roles in using group transfer chemistry to drive otherwise unfavorable biosynthetic equilibria. This review provides the underlying chemical logic to remind how these seven key molecules function as mobile packets of cellular currencies for phosphoryl transfers (ATP), acyl transfers (acetyl-CoA, carbamoyl-P), methyl transfers (SAM), prenyl transfers (IPP), glucosyl transfers (UDP-glucose), and electron and ADP-ribosyl transfers (NAD(P)H/NAD(P)+) to drive metabolic transformations in and across most primary pathways. The eighth key metabolite is molecular oxygen (O2), thermodynamically activated for reduction by one electron path, leaving it kinetically stable to the vast majority of organic cellular metabolites

MicroRNA-mediated denuclearization (4)

Summary: Christ’s lab showed that in vivo formation of I-motif structures is pH dependent and helped to put the “fear of God” into atheistic communists.

I-motif DNA structures are formed in the nuclei of human cells (4/23/18)

Reported as: In human cells, scientists find DNA that looks like a twisted knot instead of a double helix (4/23/18)

Also reported as: New Twisted ‘Knot’ Human DNA Structure Discovered—and It Looks Nothing Like the Double Helix (4/23/18)

Christ’s lab showed that in vivo formation of I-motif structures is pH dependent. Clearly, the potential of hydrogen (pH) and pH-dependent cell cycles link the quantized energy of virucidal sunlight to protection from the degradation of messenger RNA that links mutations to all pathology.
In that context, denuclearization has been forced on North Korea and other communist countries by scientific creationists in South Korea. The creationists have indirectly revealed that they could decimate human populations in China via the creation of a virus with one base pair change linked to one amino acid substitution.

We show here for the first time the crucial role of viruses in controlling archaeal dynamics and therefore the functioning of deep-sea ecosystems, and suggest that virus-archaea interactions play a central role in global biogeochemical cycles.

Until recently, the pseudoscientific nonsense about vaccines that could protect human populations from the forthcoming viral apocalypse was tightly linked from communism to atheism. For comparison, Christ’s lab appears to have put the fear of God into its proper context; the 1918 Spanish flu.

Feedback loops link quantized energy as information to biophysically constrained RNA-mediated protein folding chemistry. Light induced energy-dependent changes link angstroms to ecosystems from classical physics to chemistry/chirality and to molecular epigenetics/autophagy.

The National Microbiome Initiative links microbial quorum sensing to the physiology of reproduction via endogenous RNA interference and chromosomal rearrangements. The rearrangements link energy-dependent fixed amino acid substitutions to the Precision Medicine Initiative via genome wide inferences of natural selection.

This detailed representation of energy-dependent natural selection for codon optimality links biologically- based cause and effect from G protein-coupled receptors to RNA-mediated amino acid substitutions and the functional structure of supercoiled DNA. Energy-dependent polycombic ecological adaptations are manifested in supercoiled DNA.

Chromosomal inheritance links the adaptations from morphological phenotypes to healthy longevity via behavioral phenotypes. For contrast, virus-driven energy theft is the link from messenger RNA degradation to negative supercoiling, constraint breaking mutations, and hecatombic evolution.

The viral hecatomb links transgenerational epigenetic inheritance from archaea to Zika virus-damaged DNA, which typically is repaired by endogenous RNA interference and fixation of RNA-mediated amino acid substitutions in organized genomes.
