Ribonucleolytic activity
Webb30 dec. 2024 · Under diverse physiological conditions, RNH1 is proposed to regulate the subcellular localization and ribonucleolytic activity of ANG in different compartments [21,22]. However, strong in vivo evidence for this is still missing. RNH1 is evolved in amniotes via gene duplication and conserved among mammals. WebbValues of ribonucleolytic activity are relative to the wild-type enzyme. c Values of the equilibrium dissociation constant (or inhibition constant) are for the complex with human RI. d Values of IC 50 are for the incorporation of [methyl-3 H]thymidine into the DNA of K-562 human leukemia cells. e

WebbBacterial ribonucleases (RNases) may produce a broad spectrum of biological effects, including antiviral and antitumor activity. Mycoplasma RNases are therefore of interest. … Webb1 juli 2001 · The cytosolic ribonucleolytic activity of ribonuclease A (RNase A) and other pancreatic-type ribonucleases is limited by the presence of excess ribonuclease inhibitor (RI). RI is a 50-kDa cytosolic scavenger of pancreatic-type ribonucleases that competitively inhibits their ribonucleolytic activity.
Webb26 okt. 2024 · Ribonucleolytic activity was monitored by using the fluorogenic substrate 6-FAM–dArUdAdA–6-TAMRA [ 22 ]. Initial ( Io) and final ( If) intensities along with linear slopes (Δ I /Δ t) or the second derivative of quadratic fits (Δ 2I /Δ t2) were measured and used to calculate values of kcat / KM, as described previously [ 22 ].

Inhibition of the ribonucleolytic activity by RI was assessed by a modification of the method of Shortman (1961), who defined one unit of RI as the amount of inhibitor required to decrease by 50% the activity of 5 ng of RNase A. jp250 もてぎhttp://raineslab.com/sites/default/files/labs/raines/pdfs/Johnson2007d.pdf jp24とはWebb1 sep. 2006 · Eight members have been identified in the RNase superfamily, and whilst each has distinct biological effects, all share a common enzymic ribonucleolytic activity on RNA [5]. In angiogenin, RNase activity is directed towards 28S and 18S rRNA with the major products being 100–500 nucleotides in length [6]. jp25とはWebbAfter cleavage of the linker by the NS3 protease, the ribonucleolytic activity of the RNase A zymogen increased 105-fold. Both before and after activation, the RNase A zymogen displayed high conformational stability and evasion of the endogenous ribonuclease inhibitor protein of the mammalian cytosol. jp210801 グローエ
