Studies on Horseradish Peroxidase
The kinetics of the oxidation of p-cresol by Compound II of horseradish peroxidase has been studied by the stopped flow technique at an ionic strength of 0.11 from pH 2 to 11. In acid solution the reaction is kinetically first order in jcresol, but in the alkaline region a saturation effect attributable to complex formation is observed. At very high pH an additional second order reaction betwee...
متن کاملOxidation of indole-3-acetic Acid-amino Acid conjugates by horseradish peroxidase.
The stability of 21 amino acid conjugates of indole-3-acetic acid (IAA) toward horseradish peroxidase (HRP) was studied. The IAA conjugates of Arg, Ile, Leu, Tyr, and Val were oxidized readily by peroxidase. Those of Ala, beta-Ala, Asp, Cys, Gln, Glu, Gly, and Lys were not degraded and their recovery was above 92% after 1 hour incubation with HRP. A correlation between the stability of IAA conj...
متن کاملIsolation and Amino Acid Sequence Studies*
Glucagon was isolated from a side fraction generated during the preparation of insulin and the new pancreatic peptide, avian pancreatic polypeptide from chicken pancreas. The immunological and biological properties are similar to those of beef-pork glucagon. The amino acid composition of chicken glucagon indicates that it contains 1 more serine residue than the porcine hormone and 1 less aspart...

متن کاملCobalt-substituted horseradish peroxidase.
Horseradish peroxidase can be reconstituted with cobalt porphyrin to give a cobaltic holoenzyme having physicochemical properties quite similar to those of the native ferric protein. The cobaltic protein (Co3+HRP) can be reduced to the cobaltous form (CoHRP), the analogue of ferroperoxidase and the reduced cobalt protein can bind O2 to form an analogue of oxyferroperoxidase (Compound III). Sinc...
