  2. Biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Biosynthesis

    Biosynthetic processes are often represented via charts of metabolic pathways. 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 ...

  3. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    The biosynthetic pathway to produce vinblastine, including 30 enzymatic steps, has been transferred into yeast cells which is a convenient system to grow in large amounts. With these genetic modifications yeast can use its own metabolites geranyl pyrophosphate and tryptophan to produce the precursors of catharanthine and vindoline.

  4. Metabolic gene cluster - Wikipedia

    en.wikipedia.org/wiki/Metabolic_gene_cluster

    Metabolic gene clusters or biosynthetic gene clusters are tightly linked sets of mostly non-homologous genes participating in a common, discrete metabolic pathway. The genes are in physical vicinity to each other on the genome , and their expression is often coregulated.

  5. Shikimate pathway - Wikipedia

    en.wikipedia.org/wiki/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.

  6. Purine metabolism - Wikipedia

    en.wikipedia.org/wiki/Purine_metabolism

    This ability reflects the essentiality of purines for life. The biochemical pathway of synthesis is very similar in eukaryotes and bacterial species, but is more variable among archaeal species. [8] A nearly complete, or complete, set of genes required for purine biosynthesis was determined to be present in 58 of the 65 archaeal species studied ...

  7. Acetate pathway - Wikipedia

    en.wikipedia.org/wiki/Acetate_pathway

    The acetate pathway, also known as the polyketide pathway, is a fundamental biosynthetic route in organisms for the production of fatty acids and polyketides. This pathway operates at the interface of central metabolism and specialized metabolite synthesis, playing a crucial role in the synthesis of both primary and secondary metabolites. [2 ...

  8. Protein biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Protein_biosynthesis

    Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins.

  9. De novo synthesis - Wikipedia

    en.wikipedia.org/wiki/De_novo_synthesis

    Cholesterol also serves as a precursor for the biosynthesis of steroid hormones, bile acid [2] and vitamin D. In mammals cholesterol is either absorbed from dietary sources or is synthesized de novo. Up to 70-80% of de novo cholesterol synthesis occurs in the liver, and about 10% of de novo cholesterol synthesis occurs in the small intestine. [3]
