The nonapeptide vasopressin is synthetized as part of a longer common precursor polypeptide, together with its carrier protein neurophysin and a glycopeptide of unknown function. The gene for this common precursor has been isolated and sequenced and shown to comprise three exons encoding, respectively, the protein domains approximately corresponding to

Biosynthesis of anthracyclinones
Journal of Basic Microbiology, 1988AbstractRecent biosynthetic studies confirmed that anthraquinones are involved as intermediates in the pathway to anthracyclines. The present knowledge in this field has been reviewed. Furthermore, a new generalized order of biosynthetic intermediates from the hypothetical polyketide to aklavinone and related anthracyclinones has been proposed ...

The biosynthesis of prostaglandins
Biochimica et Biophysica Acta (BBA) - General Subjects, 1964Prostaglandins were biosynthesized to test the hypothesis that essential fatty acids could act as precursors of prostaglandins (PGS). PGE2 the PGs with the greatest biological activity were addressed first. Because of the position of the double bonds and the fact that a bended conformation of arachidonic acid suggests the possibility of trans-annular

IT was previously suggested1,2 that serine ethanolamine phosphodiester (I) was the biological precursor of lombricine (II), a substance first isolated from earthworms by Thoai and Robin3. This suggestion was strengthened by the discovery of serine ethanolamine phosphodiester in earthworms2,4 and by the finding that the serine moiety of both lombricine5

Heparin and heparan sulfate share the same polysaccharide backbone structure but differ in sulfation degree and expression pattern. Whereas heparan sulfate is found in virtually all cells of the human body, heparin expression is restricted to mast cells, where it has a function in storage of granular components such as histamine and mast cell specific ...

Biosynthesis of tetrapetalones
Organic & Biomolecular Chemistry, 2007The biosynthesis of tetrapetalones (tetrapetalones A, B, C, and D) in Streptomyces sp. USF-4727 was studied by feeding experiments with [1-13C] sodium propanoate, [1-13C] sodium butanoate, [carbonyl-13C] 3-amino-5-hydroxybenzoic acid (AHBA) hydrochloride, and [1-13C] glucose, followed by analysis of the 13C-NMR spectra.

The Biosynthesis of the Monosaccharides
1956Publisher Summary This chapter discusses the biosynthesis of the monosaccharides. The biological origin of the forty or more monosaccharides occurring in natural products is not only of academic interest but also of value from its applicability to extracellular, enzymic synthesis. The monosaccharides are closely related, one to another, in their main

SummaryThe author has reviewed the literature pertaining to the biosynthesis of collagen emphasizing those steps which are peculiar to the formation of this protein, i. e., hydroxylation of lysine and proline, the formation of subunits and of intra- and extra-molecular bonds.
