Genome conversion

Thus, the function of chemical neurotransmission is not so much to have a pre-synaptic neurotransmitter communicate with its postsynaptic receptors as to have a presynaptic genome converse with a postsynaptic genome DNA to DNA presynaptic command center to postsynaptic command center. 

Mechanisms of Genome Conversion Following rAAV Vector Transduction... 

Figure 4 Barriers to rAAV-mediated gene transfer in the airway. Numerous potential barriers can hinder successful transduction from the mucosal surface of the airway. These barriers include viral binding, endocytosis, intracellular processing and trafficking, uncoating, and single-stranded viral genome conversion.

Biochemistry resulted from the early elucidation of the pathway of enzymatic conversion of glucose to ethanol by yeasts and its relation to carbohydrate metaboHsm in animals. The word enzyme means "in yeast," and the earfler word ferment has an obvious connection. Partly because of the importance of wine and related products and partly because yeasts are relatively easily studied, yeasts and fermentation were important in early scientific development and stiU figure widely in studies of biochemical mechanisms, genetic control, cell characteristics, etc. Fermentation yeast was the first eukaryote to have its genome elucidated. 

Advances in biochemical knowledge have illuminated many areas of medicine. Conversely, the study of diseases has often revealed previously unsuspected aspects of biochemistry. The determination of the sequence of the human genome, nearly complete, will have a great impact on all areas of biology, including biochemistry, bioinformatics, and biotechnology.

An impressive one-pot six-step enzymatic synthesis of riboflavine from glucose on the laboratory scale has been reported with an overall yield of 35-50%. Six different enzymes are involved in the various synthesis steps, while two other enzymes take care for the in situ cofactor regenerations [12]. This example again shows that many more multi-enzyme cascade conversions will be developed in the near future, as a much greater variety of enzymes in sufficient amounts for organic synthetic purposes will become available through rapid developments in genomics and proteomics. 

Drugs known as integrase inhibitors and maturation inhibitors are also in development. Integrase inhibitors are designed to interfere with the integration of the viral genome while the maturation inhibitors specifically block the conversion of the HlV-1 capsid precursor, CA-SPl (p25) to mature capsid protein (p24). This blocking will result in defective core condensation and the release of noninfectious virus particles. 

Figure 1. Control of mitochondrial biogenesis by the nuclear genome. Most mitochondrial proteins, including cytochrome c, are nuclear gene products which are subsequently imported into mitochondria. Similarly, most enzymes involved in synthesis of mitochondrial phosphoplipids are encoded in the nuclear genome. Being located in the endoplasmatic reticulum, they synthesize phosphatidylcholine (PtdCho), phosphatidylserine (PtdSer), phosphatidylglycerol (PG) and phosphatidylinositol (Ptdins). The phospholipids are transferred to the outer membrane. The imported lipids then move into the inner membrane at contact sites. Mitochondria then diversify phospholipids. They decarboxylate phosphatidylserine to phosphatidylethanolamine (PtdEtN), but the main reaction is the conversion of imported phosphatidylglycerol to cardiolipin (CL). Cardiolipins localize mainly in the outer leaflet of the inner membrane.
