Phosphatase-free crystalline micrococcal nuclease.
This report relates to the preceding paper by Taniuchi and Anfinsen. Micrococcal nuclease from the strain “Foggi” has been purified from a commercially available source (Worthington). The enzyme was crystallized from an ammonium sulfate solution. The over-all purification was approximately SOO-fold with an over-all yield of about 16%. The enzyme is virtually devoid of acid and alkaline phosphat...
متن کاملThe Formation ofLipid-Linked Sugars by Cell-Free Preparations
1. A lactating rabbit mammary-gland microsomal system catalysed the incorporation of mannose from GDP-[U-14C]mannose into three endogenous acceptors, (i) polyprenyl phosphate mannose, (ii) lipid-linked oligosaccharide and (iii) protein. 2. Synthesis of polyprenyl phosphate mannose was stimulated by addition of dolichol phosphate to the incubation medium and was reversed by addition of GDP. The ...
متن کاملEvaluation of anti-malarial activity of Artemisia turcomanica and A. kopetdaghensis by cell-free β-hematin formation assay
Background and objectives:The plants of genus Artemisia (Asteraceae) have been conventionally used for prevention and medication of a number of ailments. In the present research, ten extracts with different polarities from aerial parts of two Artemisia species, A. kopetdaghensis and A. turcomanica were evaluated for their potential anti-malar...
متن کاملMacromolecular Syntheses in Cell-free Preparations
We reported (Reiner and Goodman, 1955) that formation of an inducible (adaptive) enzyme in Escherichia coli is accompanied by a modification of the ribonucleic acid (RNA) of the cell: the modified RNA specifically accelerates formation of the inducible enzyme by fresh cells. This finding agreed with our earlier work on yeast (Reiner and Spiegelman, 1948), and has been substantiated by work on v...
متن کاملThe degradation of acidsoluble collagen by rat-liver preparations.
nucleotide was increased, and, assuming that the product was derived from oligonucleotides and deoxyribonucleoside triphosphates, the synthesis amounted to 74% of the deoxyribonucleic acid primer. 4. The nucleotidyltransferase was inhibited and the lag phase extended by 3'-phosphoryl-terminal oligonucleotides from a splenic-deoxyribonuclease digest of deoxyribonucleic acid. 5. The compounds obt...
