The conformational parameters of a nuclease produced by growing cultures of Staphylococcus aureus have been determined. This nuclease exhibits both ribonuclease and deoxyribonuclease activities. It has been shown to have a pH optimum of 9.2 and an absolute requirement for calcium ions. The experimental data are compatible with a compact globular protein of mol wt 17,000 and with a helical conte...
It is shown by enzymatic digestion of chromatin from rat liver or Guerin ascites tumour (GAT) that treatments, which abolish the 180 base pair repeat, as revealed by digestion with micrococcal nuclease (shearing in salt solutions of medium ionic strength, sonication, fixation with formaldehyde in the presence of 5 M urea), have little effect on the 10 nucleotide repeat, observed in deoxyribonuc...
Serratia marcescens was isolated on a new medium-commercial deoxyribonuclease agar with the addition of cephalothin (1,000 mug/ml) and Toluidine Blue (1,000 mug/ml). It was detected in water samples even though it comprised only 0.1 to 0.0001% of the total bacterial population.
A new coordination polymer which shows an unusual 2D inorganic connectivity was constructed. This compound exhibits distinct fluorescence quenching ability to the dye-labeled single-stranded DNA probes with different lengths, based on which an analytical method was developed for the activity assay of deoxyribonuclease I.
