Polysaccharide Biosynthesis [PDF]

open access: yesThe Journal of General Physiology, 1966
Polysaccharide synthesis is discussed from the point of view of the sources of biological information that determine the structures and control the rates of synthesis of complex polysaccharides. It is concluded that three types of information contribute in important and different ways, namely enzyme specificity, primer substances, and the structure of ...

Oxytetracycline Biosynthesis [PDF]

open access: yesJournal of Biological Chemistry, 2010
Oxytetracycline (OTC) is a broad-spectrum antibiotic that acts by inhibiting protein synthesis in bacteria. It is an important member of the bacterial aromatic polyketide family, which is a structurally diverse class of natural products. OTC is synthesized by a type II polyketide synthase that generates the poly-beta-ketone backbone through successive ...

Uncovering the cytochrome P450-catalyzed methylenedioxy bridge formation in streptovaricins biosynthesis

open access: yesNature Communications, 2020
Streptovaricin C is an antibiotic containing a methylenedioxy bridge (MDB) moiety essential for its activity. Here, the authors show that a P450 monooxygenase StvP2 catalyses MDB formation, report its crystal structure in complex with the substrate, and ...

Revolution of vitamin E production by starting from microbial fermented farnesene to isophytol

open access: yesThe Innovation, 2022
Vitamin E is one of the most widely used vitamins. In the classical commercial synthesis of vitamin E (α-tocopherol), the chemical synthesis of isophytol is the key technical barrier.

Collagen Biosynthesis [PDF]

open access: yesEnvironmental Health Perspectives, 1984
Collagen is the major structural protein of the lung. At least five genetically distinct collagen types have been identified in lung tissue. However, the precise role of collagen in nonrespiratory lung function is not well understood, in part because of the difficulties inherent in studying lung collagen, regardless of the type of assay used.

Expression and gene regulatory network of SNHG1 in hepatocellular carcinoma

open access: yesBMC Medical Genomics, 2021
Background Small nucleolar RNA host gene 1 (SNHG1), a long noncoding RNA (lncRNA), is a transcript that negatively regulates tumour suppressor genes, such as p53. Abnormal SNHG1 expression is associated with cell proliferation and cancer.

Histidine Biosynthesis [PDF]

open access: yesThe Arabidopsis Book, 2011
Histidine (His) is one of the standard amino acids in proteins, and plays a critical role in plant growth and development. The chemical properties of the imidazole side group allow His to participate in acid-base catalysis, and in the co-ordination of metal ions.
