The derivative (9) of 3,6-dideoxy-a-D-xyIo-hexopyranose (abequose) was isolated from a strain of Salmonella typhimurium,16 that (10) of 3,6-dideoxy-a-D-nfco-hexopyranose (paratose) from Salmonella paratyphi,54 and a mixture of 10 and the ester (11) of 3,6-dideoxy-a-D-arabino-hexopyranose (tyvelose) from Salmonella enteritidis.,6 It was shown that these derivatives are formed from cytidine 5 -(a-D-glu-copyranosyl pyrophosphate) by treatment with nicotinamide adenine dinucleotide (NAD+) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) in the presence of cell extracts of the respective bacterial strain. For example, formation of 9 is characteristic of preparations from Salmonella, group B,55,56 or Pasteurella pseudotuberculosis, type II.56 The derivative 10 was obtained with extracts of Salmonella, group A,56 and Pasteurella pseudotuberculosis, type I and III,56 and a mixture of 10 and 11 with those of Salmonella, group D,55-60 or Pasteurella pseudotuberculosis, type IV 56.59,60 Under similar conditions, the ester (12) of cytidine 5 -pyro-...

Two unusual glycosyl esters of cytidine 5 -pyrophosphate were found in extracts of Azotobacter vinelandii,62 The branched-chain, O-methylated heptose called vinelose was identified as the glycosyl component, and the structures 13 and 14 were assigned to these... [Pg.317]

The esters of cytidine 5 -pyrophosphate with 6-deoxy-a-D-xylo-hexopyranos-4-ulose (15) and 3,6-dideoxy-a-D-ert/f/iro-hexopyranos-4-ulose (16) are probably normal metabolites in Gram-negative bac-... [Pg.318]

Facile cleavage under alkaline conditions has also been observed for ribitol192 and glycerol200 esters of cytidine 5 -pyrophosphate. Cytidine 5 -(3,6-dideoxy-a-D-arahtno-hexopyranosyl pyrophosphate)... [Pg.359]

More-detailed studies of enzyme specificity towards the structure of the nucleoside residue have been performed with the sucrose synthetase of pea seedlings,339,384,501,502 and with wheat-germ arbutin synthetase.339,364,503 Neither enzyme can use the cytidine,504 isocyti-dine, or N3-methyluridine derivatives as substrates. On the other hand, the a-D-glucopyranosyl pyrophosphate esters of 4-thiouri-... [Pg.394]

The third acylation requires the phosphate to act as the acylating agent and a polar alcohol to be introduced to form a phosphate ester. This reaction actually occurs by the activation of the phosphate as a pyrophosphate. Pyrophosphates are really acid anhydrides so it is not surprising that they act as acylating agents. The first step is a reaction with cytidine triphosphate (CTP) doing a job we might expect from ATP. [Pg.1376]

The pathway for de novo synthesis of dolichol phosphate is the same as for cholesterol until production of famesyl pyrophosphate (Chapter 19). Two salvage pathways provide for the reutilization of dolichol and dolichol pyrophosphate once transfer of oligosaccharide from the dolichol to glycoprotein has occurred. A significant portion of the dolichol in liver is present as the free alcohol or as a fatty acid ester, and dolichol absorbed from the diet may enter this pool. Phosphorylation of dolichol is catalyzed by a dolichol kinase via cytidine triphosphate (CTP). Removal of one phosphate... [Pg.312]

The enzyme purified from bull semen dephosphorylates the 5 -phosphate esters of adenosine, uridine, cytidine, guanosine, nicotinamide riboside, and the 5 -phosphate esters of deoxynucleosides, but is inactive with adenosine pyrophosphates and substrates which bear other substituents on the ribose, e.g., adenosine 2, 5 -diphosphate (124). However 5 -nucleo-tidase from potato can hydrolyze the 5 -phosphate of this diphosphate... [Pg.479]
