The configuration and location of the ribosidic linkage in the prosthetic group of citrate lyase (Klebsiella aerogenes)
The structure of the prosthetic group of citrate lyase (Klebsiella aerogenes) was studied by nuclear magnetic resonance and mass spectrometry. The spectra at 360 MHz of the nucleoside moiety (2'-ribosyladenosine) show the absence of 2'-hydroxyl proton, thus confirming the 2' position...

Summary: | The structure of the prosthetic group of citrate lyase (Klebsiella aerogenes) was studied by nuclear magnetic resonance and
mass spectrometry. The spectra at 360 MHz of the nucleoside moiety (2'-ribosyladenosine) show the absence of 2'-hydroxyl proton,
thus confirming the 2' position as the site of attachment of the second ribose moiety to the dephospho-CoA. This glycosidic
linkage is found to be alpha(1" leads to 2') and is identical to that of poly(ADP-ribose). Studies of permethylation products
by mass spectrometry support the above conclusion regarding the location of the ribosidic linkage. |
