The terminal nucleotides of 70 S RNA extracted from murine leukemia virus (AKR, L-1 strain MLV) have been characterized by the introduction at the 5′-terminus of 32 P and by chemical conversion of the 3-terminal sugar residue to a tri[ 3 H]alcohol.

Summary The virus proteins, reverse transcriptase (RT) and p30, were found to increase with time in the subcellular fractions of lymphocytic tissue from either the thymus or spleen of AKR mice with spontaneous lymphocytic leukaemia. Significant level

Human spleen RNase was purified using an immunoabsorbant produced with anti-human liver RNase serum. The purification was more rapid than the procedure used to purify the liver RNase, yet the final specific activity was similar. Problems encountered

The Citrobacter ribonuclease, an enzyme that cleaves preferentially phosphodiester bonds of ribonucleic acid at uridylic acid residues, has been shown to bind the polyamines, putrescine, spermidine, and spermine. The binding of spermidine insures the

The polyamines have been used to activate staphylococcal nuclease for degradation of both RNA and DNA in the absence of calcium ions. If low concentrations of calcium are added to the polyamine-activated enzyme, up to double the expected activity (ba

Serum RNase levels were measured in 34 patients with multiple myeloma and compared with 51 normal controls and 28 non-myeloma patients on chronic hemodialysis. Nineteen of the myeloma patinets with creatinine clearance (CCr) greater than 50 ml/minute

A ribonuclease, purified some 2700-fold from human plasma, exhibited a strong predilection for the hydrolysis of internucleotide bonds containing cytidylic acid. Analysis of [3'-32P]- and [5'-32P]phosphoryl-terminal fragments obtained after enzymic d

The effect of polyadenylic acid, a potent inhibitor of mammalian and bacterial RNAses, on the binding of human liver RNAse to its antibody was studied. To do this, a human liver RNAse antibody was immobilized on Sepharose 4B. Examination of the abili

The RNase activity observed in the sera of leukemic guinea pigs was compared to that observed in white blood cell (WBC) lysates of the same animals. The WBC-associated RNase activity directed against polyuridylic acid decreased with the progression o

Rapid RNA sequencing technology was used to determine if the base specificities of an RNase recently purified from chicken liver would prove useful for RNA sequence analysis. Escherichia coli 5 S [5'-32P]rRNA or yeast 5.8 S [5'-32P]rRNA was digested
