Purification of glycineamide ribonucleotide transformylase

Biochemical and Biophysical Research Communications, 1978
Abstract Glycineamide ribonucleotide transformylase has been purified 240-fold from chicken liver along with formyl-methenyl-methylenetetrahydrofolate synthetase (combined), through seven purification steps including a glycineamide ribonucleotide affinity column and a 10-formyl synthetase specific MgATP elution from hydroxylapatite.

Structural features of ribonucleotide reductase

Proteins: Structure, Function, and Bioinformatics, 1986
AbstractHerpes simplex virus type 1 (HSV‐1) encodes a ribonucleotide reductase which comprises two polypeptides with sizes of 136,000 (RR1) and 38,000 mol. wt. (RR2). We have determined the entire DNA sequence specifying HSV‐1 RR1 and have identified two adjacent open reading frames in varicella‐zoster virus (VZV) which have homology to HSV RR1 and RR2;

Enzymatic Reduction of Ribonucleotides

1967
Publisher Summary This chapter describes the enzymatic reduction of ribonucleotides. The formation of deoxyribonucleotides from ribonucleotides in a cell-free system is discussed in this chapter. It was important to establish that the observed transfer of isotope from cytidine monophosphate (CMP) to dCMP occurred only by direct reduction of the ...

The nature of the isomerism in yeast ribonucleotides

Biochimica et Biophysica Acta, 1953
Abstract The isomeric nucleotides obtained upon the hydrolysis of ribose nucleic acid have been studied. The nucleotides were dephosphorylated enzymically, and the resulting nucleosides subjected to further degradation by nucleoside deaminases.

Thin-layer electrophoresis of ribonucleotides

Analytical Biochemistry, 1969
Abstract Electrophoresis on thin layers of cellulose of an alkaline hydrolyzate of RNA provides an easy and reproducible method for base ratio determinations. Separation of a nucleotide mixture (20–40 μg) is completed in 90 min at 4°C and requires only conventional equipment.

Transcriptional Regulation of Ribonucleotide Reductase

1991
The Swiss 3T3 cell system can be used to explore the molecular mechanism of proliferation. These fibroblasts can be arrested in a quiescent homogeneous Go/G1 state by serum deprivation and then induced to proliferate by a variety of mitogenic growth factors (1). An important endeavour in determining the basis of growth factor action is to elucidate the
