ResumoThe enzyme of Myrothecium verrucaria spores has an indicated absolute specificity for l-ascorbic acid and is irreversibly inactivated by d-isoascorbic acid, oxygen being necessary for this reaction. It is postulated that a stable ternary complex is formed between enzyme, isoascorbate, and oxygen. Studies of the inactivation show it to be markedly affected by pH and to have a positive temperature coefficient. Results of further studies on certain characteristics of the enzyme are reported.
