In this overview we can see how the amino acid pool is added to from dietary protein and how the intracellular proteins circlulate these free amino acids in a continuous cycle of synthesis and breakdown. Excess amino acids are metabolised (not stored for use as potential energy because this can be done more efficiently using other energy sources). The carbon skeleton, as an α-keto acid, is fed ...

The enediyne antitumor antibiotic C-1027 chromoprotein is produced by Streptomyces globisporus. The biosynthesis of the (S)-3-chloro-4,5-dihydroxy-beta-phenylalanine moiety (boxed) of the C-1027 chromophore (1) from l-tyrosine (3) and its incorporation into 1 are catalyzed by six enzymes: SgcC, SgcC1, SgcC2, SgcC3, SgcC4, ShcC5. In vivo and in vitro characterization of these enzymes delineated ...

Halogenation plays a significant role in the activity of the glycopeptide antibiotics (GPAs), although up until now the timing and therefore exact substrate involved was unclear. Here, we present results combined from in vivo and in vitro studies that reveal the substrates for the halogenase enzymes from GPA biosynthesis as amino acid residues bound to peptidyl carrier protein (PCP)-domains fro...

MicroRNAs (miRNAs) related to phytohormone signal transduction and self-incompatibility may play an important role in the xenia effect. However, associated research this area is still lacking rabbiteye blueberry ( Vaccinium ashei ). In study, we identified miRNAs, predicted their target genes, performed functional enrichment analysis of screened for miRNAs signaling self-incompatibility. A tota...

Considerable interest has developed in recent years in the separation of the amino acid-specific “soluble’‘-fraction ribonucleic acids because of the probable role of these RNAs in protein biosynthesis (l-5) and because the elucidation of the structures of the different amino acid-specific RNAs may lead to an understanding of the mechanism of information transfer by nucleic acids. Preliminary s...

a study was conducted to evaluate efficacyof wheat based vs. corn based diets on growth performance, carcass traits,blood parameters, jejunum morphological development, immunity, cecal microflora and excreta moisture in broiler chicks fed according to digestible essential amino acid profile. one hundred forty day old ross 308 male broiler chicks randomly distributed into ten separated floor pen...

brachystegia eurycoma is predominantly grown in the eastern region of nigeria. its seed is used in food majorly as a soup condiment, flavouring agent and soup thickener. the proximate, mineral and amino acid compositions were determined on raw and processed seeds (boiled, fermented and roasted) using standard analytical techniques. the processing methods showed deviations in nutrients from the ...
