Association of Inosine and Cytidine

open access: yesBiophysical Journal, 1971
A rigorous theory for the analysis of an associating system involving two different monomer units, which may also undergo self-association, has been developed. In the present paper the application of the theory to actual data is demonstrated for the first time.

The site of ribonucleic acid synthesis in the isolated nucleus [PDF]

open access: yes, 1961
There is still controversy concerning the primary site of RNA synthesis in the cell.(1) When tissues are radioautographed after administration of radioactive inorganic phosphorus or radioactive RNA(2) precursors such as tritiated uridine or cytidine, it ...

Cytidine triphosphate:phosphatidic acid cytidyltransferase in Escherichia coli

open access: yesJournal of Lipid Research, 1968
An enzyme has been found in particulate fractions of Escherichia coli that catalyzes the incorporation of cytidine triphosphate (CTP) into lipid in the presence of exogenous phosphatidic acid and Mg++. The product has been identified enzymatically and by

Salvage enzymes in nucleotide biosynthesis [PDF]

open access: yes, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Synthesis of ethanolamine phosphoglycerides by human platelets.

open access: yesJournal of Lipid Research, 1975
Platelet homogenates contain an ethanolaminephosphotransferase (EC 2.7.8.1) that catalyzes the synthesis of ethanolamine phosphoglycerides from cytidine-5‘-diphosphate ethanolamine and 1-radyl-2-acyl-sn-glycerols.

Intrinsic immunity against retrotransposons by APOBEC cytidine deaminases

open access: yesFrontiers in Microbiology, 2013
Over 40% of the human genome is recognizable as having been derived from ancient retroelements, transported by an intracellular copy-and-paste process involving an RNA intermediate, with an additional few percent classified as DNA transposable elements ...

In vitro and in vivo modification of Neisseria gonorrhoeae lipooligosaccharide epitope structure by sialylation. [PDF]

open access: yes, 1990
After growth of gonococci in the presence of cytidine monophospho-N-acetyl-neuraminic acid (CMP-NANA), their 4.5-kD lipooligosaccharide (LOS) component was increased by approximately 400 daltons, whereas the LOS of strains lacking the 4.5-kD component ...

The correlation of RNase A enzymatic activity with the changes in the distance between Nepsilon2-His12 and N delta1-His119 upon addition of stabilizing and destabilizing salts. [PDF]

open access: yes
The effect of stabilizing and destabilizing salts on the catalytic behavior of ribonuclease A (RNase A) was investigated at pH 7.5 and 25 degrees C, using spectrophotometric, viscometric and molecular dynamic methods.
