Enzymatic phosphorylation of butyrate.
Conservation of thiol ester bond energy through a reaction sequence involving phosphorolysis of acetyl coenzyme A by phosphotransacetylase (1, 2) and the subsequent formation of adenosine triphosphate from adenosine diphosphate and acetyl phosphate by acetokinase (3, 4) is well established in fermentative bacteria. A similar reaction sequence involving butyryl coenzyme A, phosphotransbutyrylase...
متن کاملEnzymatic phosphorylation of acetate.
The metabolic utilization of acetate (oxidation via the citric acid cycle, synthesis of higher fatty acids, cholesterol, and possibly other compounds) requires a preliminary activation through conversion to acetyl C0A.l Two main mechanisms are known to bring about this activation (2). One of these mechanisms, utilized by animal tissues, yeast, and some bacteria, seems to involve a single enzyme...
متن کاملEnzymatic phosphorylation of macrolide antibiotics.
Five macrolide antibiotics (erythromycin A, 1; oleandomycin, 3a; tylosin, 4a; spiramycins, 5a; leucomycin A3, 6a) have been phosphorylated enzymatically using cell-free extracts derived from Streptomyces coelicolor UC 5240. The necessary cofactors and the rates of the conversion have been determined.
متن کاملThe enzymatic phosphorylation of riboflavin.
While the existence and coenzymatic function of riboflavin-5-phosphate’ have been recognized for some time, the meansby which this substance is synthesized from the free vitamin have not been satisfactorily demonstrated. Verzar and coworkers (3,4) have reported extensive phosphorylation of riboflavin by means of inorganic phosphate in preparations of intestinal mucosa. The synthesis of FMN by s...
متن کاملVGB3 Induces Apoptosis by Inhibiting Phosphorylation of NF-κB p65 at Serine 536 in the Human Umbilical Vein Endothelial Cells
Background and objectives: Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) inhibition results in an increase in apoptosis. It has been demonstrated that NF-κB subunit p65 phosphorylation at the IκB kinase phosphorylation site serine 536 (Ser536) is essential for the NF-κB nuclear translocation and activation. Therefore, NF-κB can be downregulated by suppressing its phosph...
