The disulfide variants catalyze the cleavage of poly(cytidylic acid) with values of kcat/Km that are 2- to 40-fold less than that of wild-type RNase A. Poly C 267-287 ribonuclease pancreatic Bos taurus 362-369 11742128-2 2002 Oligocytidylic acids, ranging from dinucleotides to heptanucleotides, were obtained by RNase A digestion of poly(C). Poly C 108-115 ribonuclease pancreatic Bos taurus 87-94 9724524-6 1998 Wild-type RNase A and the K66A, K7A/R10A, and K7A/R10A/K66A variants were evaluated as catalysts for the cleavage of poly(cytidylic acid) [poly(C)] and for their abilities to bind to single-stranded DNA, a substrate analogue. Poly C 117-137 ribonuclease pancreatic Bos taurus 10-17 9724524-6 1998 Wild-type RNase A and the K66A, K7A/R10A, and K7A/R10A/K66A variants were evaluated as catalysts for the cleavage of poly(cytidylic acid) [poly(C)] and for their abilities to bind to single-stranded DNA, a substrate analogue. Poly C 139-146 ribonuclease pancreatic Bos taurus 10-17 9724524-8 1998 The kcat/Km values for poly(C) cleavage by the K66A, K7A/R10A, and K7A/R10A/K66A variants were 3-fold, 60-fold, and 300-fold lower, respectively, than that of wild-type RNase A. Poly C 23-30 ribonuclease pancreatic Bos taurus 169-176 10504400-11 1999 On the contrary, the activity of the RNase A oligomers, from dimer to pentamer, on yeast RNA and poly(C) (Kunitz assay) is lower than that of monomeric RNase A. Poly C 97-103 ribonuclease pancreatic Bos taurus 37-44 10220316-6 1999 T45G RNase A, which catalyzes the processive cleavage of poly(A) but the distributive cleavage of poly(cytidylic acid) [poly(C)], has the same preference. Poly C 98-118 ribonuclease pancreatic Bos taurus 5-12 10220316-6 1999 T45G RNase A, which catalyzes the processive cleavage of poly(A) but the distributive cleavage of poly(cytidylic acid) [poly(C)], has the same preference. Poly C 120-127 ribonuclease pancreatic Bos taurus 5-12 8844858-6 1996 The free energies with which Y97F, Y97A, and Y97G RNase A bind to the rate-limiting transition state during the cleavage of poly(cytidylic acid) are diminished by 0.74, 3.3, and 3.8 kcal/mol, respectively.
