Bioretrosynthesis. Bioretrosynthesis is a technique for synthesizing organic chemicals from inexpensive precursors and evolved enzymes. [1] The technique builds on the retro-evolution hypothesis proposed in 1945 by geneticist Norman Horowitz. [2]
An arylcyclohexylamine is composed of a cyclohexylamine unit with an aryl moiety attachment. The aryl group is positioned geminal to the amine. In the simplest cases, the aryl moiety is typically a phenyl ring, sometimes with additional substitution. The amine is usually not primary; secondary amines such as methylamine or ethylamine, or ...
A linear biochemical pathway is a chain of enzyme-catalyzed reaction steps where the product of one reaction becomes the substrate for the next reaction. The molecules progress through the pathway sequentially from the starting substrate to the final product. Each step in the pathway is usually facilitated by a different specific enzyme that ...
A particular biosynthetic pathway may be located within a single cellular organelle (e.g., mitochondrial fatty acid synthesis pathways), while others involve enzymes that are located across an array of cellular organelles and structures (e.g., the biosynthesis of glycosylated cell surface proteins).
Shikimate pathway. The shikimate pathway ( shikimic acid pathway) is a seven-step metabolic pathway used by bacteria, archaea, fungi, algae, some protozoans, and plants for the biosynthesis of folates and aromatic amino acids ( tryptophan, phenylalanine, and tyrosine ). This pathway is not found in mammals.
Fatty acid synthesis. In biochemistry, fatty acid synthesis is the creation of fatty acids from acetyl-CoA and NADPH through the action of enzymes called fatty acid synthases. This process takes place in the cytoplasm of the cell. Most of the acetyl-CoA which is converted into fatty acids is derived from carbohydrates via the glycolytic pathway.
Polyketide synthase. Polyketide synthases ( PKSs) are a family of multi- domain enzymes or enzyme complexes that produce polyketides, a large class of secondary metabolites, in bacteria, fungi, plants, and a few animal lineages. The biosyntheses of polyketides share striking similarities with fatty acid biosynthesis.
Pathway of plasmalogen synthesis. Biosynthesis of plasmalogens begins with association of peroxisomal matrix enzymes GNPAT (glycerone phosphate acyl transferase) and AGPS (alkyl-glycerone phosphate synthase) on the luminal side of the peroxisomal membrane. [12] These two enzymes can interact with each other to increase efficiency.
