Deoxyribonuclease Activity
The relationship of catalase, cystinase, and deoxyribonuclease activity to toxinogeny in Corynebacterium diphtheriae was examined. Mutants deficient in each activity were isolated after mutagenization of strain C4 with nitrosoguanidine. All mutants were converted to toxinogeny after lysogenization with beta-converting phage, thus establishing that there is no absolute link between toxin product...
متن کاملStructure of acid deoxyribonuclease
Deoxyribonuclease II (DNase II) is also known as acid deoxyribonuclease because it has optimal activity at the low pH environment of lysosomes where it is typically found in higher eukaryotes. Interestingly, DNase II has also been identified in a few genera of bacteria and is believed to have arisen via horizontal transfer. Here, we demonstrate that recombinant Burkholderia thailandensis DNase ...
متن کاملDeoxyribonuclease from Salmon Testes
A procedure is described for the purification of salmon testis deoxyribonuclease II by means of acid extraction, fractional precipitation with ammonium sulfate, heat denaturation of extraneous proteins, and ethanol fractionation. This process separates the deoxyribonuclease activity from that of ribonuclease, phosphatase, phosphodiesterase, and protease. Over 50 per cent of the activity is reta...
متن کاملBovine pancreatic deoxyribonuclease D.
Of the four deoxyribonucleases, DNases A, B, C, and D, observable by chromatography of preparations of the pancreatic enzyme on cellulose phosphate, DNase D, the component present in the smallest amount, has not been previously characterized. Peptide maps show that the sequence of the amino acid residues in the polypeptide chain of DNase D is indistinguishable from that of DNase C; analysis of ...
متن کاملPorcine Spleen Deoxyribonuclease II
Porcine spleen DNase II, a lysosomal acid hydrolase, is a noncovalently linked azb heterodimer (Liao, T.-H. (1985) J. Biol. Chem. 260, 10708–10713). The a subunit, after disulfide cleavage, yields two chains, a1 and a2. The complete amino acid sequences of the a1, b, and a2 chains were elucidated by protein sequencing, and the pairings of one interchain disulfide between a1 and a2 and of three ...
